Math | 19 | src/main/java/org/apache/commons/math3/optimization/direct/CMAESOptimizer.java | 504 | 561 | Wide bounds to CMAESOptimizer result in NaN parameters passed to fitness function | If you give large values as lower/upper bounds (for example -Double.MAX_VALUE as a lower bound), the optimizer can call the fitness function with parameters set to NaN. My guess is this is due to FitnessFunction.encode/decode generating NaN when normalizing/denormalizing parameters. For example, if the difference between the lower and upper bound is greater than Double.MAX_VALUE, encode could divide infinity by infinity. | private void checkParameters() {

Compress | 41 | src/main/java/org/apache/commons/compress/archivers/zip/ZipArchiveInputStream.java | 219 | 324 | ZipArchiveInputStream.getNextZipEntry() should differentiate between "invalid entry encountered" and "no more entries" | ZipArchiveInputStream.getNextZipEntry() currently returns null if an invalid entry is encountered. Thus, it's not possible to differentiate between "no more entries" and "invalid entry encountered" conditions.
Instead, it should throw an exception if an invalid entry is encountered.
I've created a test case and fix. I will submit a pull request shortly. | public ZipArchiveEntry getNextZipEntry() throws IOException {

Math | 2 | src/main/java/org/apache/commons/math3/distribution/HypergeometricDistribution.java | 267 | 269 | HypergeometricDistribution.sample suffers from integer overflow | Hi, I have an application which broke when ported from commons math 2.2 to 3.2. It looks like the HypergeometricDistribution.sample() method doesn't work as well as it used to with large integer values -- the example code below should return a sample between 0 and 50, but usually returns -50.
{code}
import org.apache.commons.math3.distribution.HypergeometricDistribution;
public class Foo {
public static void main(String[] args) {
HypergeometricDistribution a = new HypergeometricDistribution(
43130568, 42976365, 50);
System.out.printf("%d %d%n", a.getSupportLowerBound(), a.getSupportUpperBound()); // Prints "0 50"
System.out.printf("%d%n",a.sample()); // Prints "-50"
}
}
{code}
In the debugger, I traced it as far as an integer overflow in HypergeometricDistribution.getNumericalMean() -- instead of doing
{code}
return (double) (getSampleSize() * getNumberOfSuccesses()) / (double) getPopulationSize();
{code}
it could do:
{code}
return getSampleSize() * ((double) getNumberOfSuccesses() / (double) getPopulationSize());
{code}
This seemed to fix it, based on a quick test. | public double getNumericalMean() {
return (double) (getSampleSize() * getNumberOfSuccesses()) / (double) getPopulationSize();
} | public double getNumericalMean ( ) { return ( double ) ( getSampleSize ( ) * getNumberOfSuccesses ( ) ) / ( double ) getPopulationSize ( ) ; } | public double getNumericalMean() {

JacksonDatabind | 85 | src/main/java/com/fasterxml/jackson/databind/ser/std/DateTimeSerializerBase.java | 48 | 95 | `DateTimeSerializerBase` ignores configured date format when creating contextual | `DateTimeSerializerBase#createContextual` creates a new serializer with `StdDateFormat.DATE_FORMAT_STR_ISO8601` format instead of re-using the actual format that may have been specified on the configuration. See the following code:
```
final String pattern = format.hasPattern()
? format.getPattern()
: StdDateFormat.DATE_FORMAT_STR_ISO8601;
```
Using the `@JsonFormat` annotation on a field will therefore reset the format to Jackson's default even if the annotation doesn't specify any custom format.
`DateBasedDeserializer#createContextual` behaves differently and tries to re-use the configured format:
```
DateFormat df = ctxt.getConfig().getDateFormat();
// one shortcut: with our custom format, can simplify handling a bit
if (df.getClass() == StdDateFormat.class) {
...
StdDateFormat std = (StdDateFormat) df;
std = std.withTimeZone(tz);
...
} else {
// otherwise need to clone, re-set timezone:
df = (DateFormat) df.clone();
df.setTimeZone(tz);
}
```
Shouldn't the serializer follow the same approach ?

JacksonDatabind | 1 | src/main/java/com/fasterxml/jackson/databind/ser/BeanPropertyWriter.java | 582 | 624 | NULL values are duplicated when serializing as array [via @JsonFormat(shape = JsonFormat.Shape.ARRAY)] | Example:
``` java
public class TestOuter {
@JsonFormat(shape = JsonFormat.Shape.ARRAY)
public ArrayList<TestInner> array;
public TestOuter() {
this.array = new ArrayList<TestInner>();
this.array.add(new TestInner(1, "one"));
this.array.add(new TestInner(0, null));
}
private class TestInner {
public int i;
public String mayBeNull;
public TestInner(int i, String s) {
this.i = i;
this.mayBeNull = s;
}
}
}
```
Serializing an instance of TestOuter will produce the following incorrect result (as of Jackson 2.2.1):
``` json
"array": [[1, "one"], [0, null, null]]
```
where the null value is duplicated. The expected result would be:
``` json
"array": [[1, "one"], [0, null]]
```
I tracked the issue down to:
``` java
package com.fasterxml.jackson.databind.ser;
// ...
public class BeanPropertyWriter {
// ...
public void serializeAsColumn(Object bean, JsonGenerator jgen, SerializerProvider prov)
throws Exception
{
Object value = get(bean);

} else { // can NOT suppress entries in tabular output
jgen.writeNull();
}
}
// otherwise find serializer to use
JsonSerializer<Object> ser = _serializer;
// ... ...
```
where I suspect there is a missing "return", to exit the function once handling of the null value in the dedicated branch is done.
As it is now, a null value is first serialized in the dedicated branch (jgen.writeNull()), and then execution continues on the "normal" (non-null) path and eventually the value is serialized once again.

Math | 74 | src/main/java/org/apache/commons/math/ode/nonstiff/EmbeddedRungeKuttaIntegrator.java | 191 | 359 | Wrong parameter for first step size guess for Embedded Runge Kutta methods | In a space application using DOP853 i detected what seems to be a bad parameter in the call to the method initializeStep of class AdaptiveStepsizeIntegrator.
Here, DormandPrince853Integrator is a subclass for EmbeddedRungeKuttaIntegrator which perform the call to initializeStep at the beginning of its method integrate(...)
The problem comes from the array "scale" that is used as a parameter in the call off initializeStep(..)
Following the theory described by Hairer in his book "Solving Ordinary Differential Equations 1 : Nonstiff Problems", the scaling should be :
sci = Atol i + |y0i| * Rtoli
Whereas EmbeddedRungeKuttaIntegrator uses : sci = Atoli
Note that the Gragg-Bulirsch-Stoer integrator uses the good implementation "sci = Atol i + |y0i| * Rtoli " when he performs the call to the same method initializeStep(..)
In the method initializeStep, the error leads to a wrong step size h used to perform an Euler step. Most of the time it is unvisible for the user.
But in my space application the Euler step with this wrong step size h (much bigger than it should be) makes an exception occur (my satellite hits the ground...)
To fix the bug, one should use the same algorithm as in the rescale method in GraggBulirschStoerIntegrator
For exemple :
final double[] scale= new double[y0.length];;
if (vecAbsoluteTolerance == null) {
for (int i = 0; i < scale.length; ++i) {
final double yi = Math.max(Math.abs(y0[i]), Math.abs(y0[i]));
scale[i] = scalAbsoluteTolerance + scalRelativeTolerance * yi;
}
} else {
for (int i = 0; i < scale.length; ++i) {
final double yi = Math.max(Math.abs(y0[i]), Math.abs(y0[i]));
scale[i] = vecAbsoluteTolerance[i] + vecRelativeTolerance[i] * yi;
}
}
hNew = initializeStep(equations, forward, getOrder(), scale,
stepStart, y, yDotK[0], yTmp, yDotK[1]);
Sorry for the length of this message, looking forward to hearing from you soon

JacksonDatabind | 102 | src/main/java/com/fasterxml/jackson/databind/ser/std/DateTimeSerializerBase.java | 61 | 136 | Cannot set custom format for `SqlDateSerializer` globally | Version: 2.9.5
After https://github.com/FasterXML/jackson-databind/issues/219 was fixed, the default format for `java.sql.Date` serialization switched from string to numeric, following the default value of `WRITE_DATES_AS_TIMESTAMPS`.
In order to prevent breaks, I want `java.sql.Date` to serialize as a string, without changing behavior for `java.util.Date` (which has always serialized as a number by default).
According to https://github.com/FasterXML/jackson-databind/issues/219#issuecomment-370690333, I should be able to revert the behavior for `java.sql.Date` only with
```
final ObjectMapper mapper = new ObjectMapper();
mapper.configOverride(java.sql.Date.class).setFormat(JsonFormat.Value.forPattern("yyyy-MM-dd"));
```
This doesn't seem to do anything, though. Looking at the code, it looks like it's because the custom format isn't actually added to `SqlDateSerializer` except in the `createContextual` method (https://github.com/FasterXML/jackson-databind/blob/master/src/main/java/com/fasterxml/jackson/databind/ser/std/DateTimeSerializerBase.java#L59).
For now, I've reverted this behavior with
```
mapper.registerModule(new SimpleModule() {
{
addSerializer(
java.sql.Date.class,
new SqlDateSerializer().withFormat(false, new SimpleDateFormat("yyyy-MM-dd"))
);
}
});
```
but it seems pretty hacky so I'd prefer the other method if possible.

It is a bug but it is due to well defined behaviour (so that makes me feel a
little better about myself ;). To support *special*
(well I call them special anyway) like -Dsystem.property=value we need to be
able to examine the first character of an option. If the first character is
itself defined as an Option then the remainder of the token is used as the
value, e.g. 'D' is the token, it is an option so 'system.property=value' is the
argument value for that option. This is the behaviour that we are seeing for
your example.
't' is the token, it is an options so 'arget' is the argument value.
I suppose a solution to this could be to have a way to specify properties for
parsers. In this case 'posix.special.option == true' for turning
on *special* options. I'll have a look into this and let you know.
Just to keep track of this and to get you used to how we operate, can you log a
bug in bugzilla for this.
Thanks,

JacksonCore | 26 | src/main/java/com/fasterxml/jackson/core/json/async/NonBlockingJsonParser.java | 87 | 112 | Non-blocking parser reports incorrect locations when fed with non-zero offset | When feeding a non-blocking parser, the input array offset leaks into the offsets reported by `getCurrentLocation()` and `getTokenLocation()`.
For example, feeding with an offset of 7 yields tokens whose reported locations are 7 greater than they should be. Likewise the current location reported by the parser is 7 greater than the correct location.
It's not possible for a user to work around this issue by subtracting 7 from the reported locations, because the token location may have been established by an earlier feeding with a different offset.

Mockito | 5 | src/org/mockito/internal/verification/VerificationOverTimeImpl.java | 75 | 99 | Mockito 1.10.x timeout verification needs JUnit classes (VerifyError, NoClassDefFoundError) | If JUnit is not on the classpath and mockito is version 1.10.x (as of now 1.10.1 up to 1.10.19) and the code is using the timeout verification which is not supposed to be related to JUnit, then the JVM may fail with a `VerifyError` or a `NoClassDefFoundError`.
This issue has been reported on the [mailing list](https://groups.google.com/forum/#!topic/mockito/A6D7myKiD5k) and on [StackOverflow](http://stackoverflow.com/questions/27721621/java-lang-verifyerror-with-mockito-1-10-17)
A simple test like that with **TestNG** (and no JUnit in the class path of course) exposes the issue:
```
import org.testng.annotations.Test;
import java.util.Observable;
import static org.mockito.Mockito.*;
public class VerifyErrorOnVerificationWithTimeoutTest {
@Test public void should_not_throw_VerifyError() {
verify(mock(Observable.class), timeout(500)).countObservers();
}
}
```
With TestNG 5.13.1, the stack trace is :
```
java.lang.VerifyError: (class: org/mockito/internal/verification/VerificationOverTimeImpl, method: verify signature: (Lorg/mockito/internal/verification/api/VerificationData;)V) Incompatible argument to function
at org.mockito.verification.Timeout.<init>(Timeout.java:32)
at org.mockito.verification.Timeout.<init>(Timeout.java:25)
at org.mockito.Mockito.timeout(Mockito.java:2103)
at com.example.UserServiceImplTest.test(UserServiceImplTest.java:26)
```
TestNG includes a dependency on JUnit 3.8.1, which has the `junit.framework.ComparisonFailure`, but the JVM cannot perform the linking at runtime (`VerifyError` extends `LinkageError`), probably because for the JVM there's some incompatible changes in this class between version 3.x and 4.x.
Note that Mockito is compiled against JUnit 4.x. This also reveal that Mockito is not anymore compatible with JUnit 3.x.
With TestNG 6.8.13, the stack trace is :
```

Indeed JUnit is not anymore a dependency of TestNG.
In this specific case the issue is that the `Timeout` class wraps a `VerficationOverTimeImpl` that uses in try/catch block the exception `org.mockito.exceptions.verification.junit.ArgumentsAreDifferent` which extends `junit.framework.ComparisonFailure`.
At this time it seems to be the only place where JUnit is needed, this affect the following public API :
``` java
Mockito.timeout(...)
Mockito.after(...)

JacksonDatabind | 50 | src/main/java/com/fasterxml/jackson/databind/deser/BeanDeserializer.java | 376 | 474 | `@JsonIdentityInfo` deserialization fails with combination of forward references, `@JsonCreator` | As a follow-up to bug #1255, the patch I provided exposes related deserialization problems.
I have attached a small project ('jackson-test.zip') to demonstrate these issues. When run with both patches from #1255, the output is provided in the attached 'both.txt'. When run with just the first patch from #1255, the output is provided in the attached 'first.txt'.
Important points:
1. When the object expressed as an id is contained within a collection or map (List in this example), deserialization works correctly. When it is a field of an object, deserialization is broken.
2. This particular example doesn't have forward references, but it does have cycles. Nevertheless, I have seen situations where non-cyclical forward-references also do not deserialize properly, with the same caveat as in 1.

JacksonDatabind | 27 | src/main/java/com/fasterxml/jackson/databind/deser/BeanDeserializer.java | 773 | 857 | Problem deserializing External Type Id if type id comes before POJO | (note: seems to be similar or related to https://github.com/FasterXML/jackson-module-afterburner/issues/58)
With 2.6, looks like handling of External Type Id is broken in some rare (?) cases; existing unit tests did not catch this. At this point I am speculating this is due to some refactoring, or change to use more efficient 'nextFieldName()' method.
