DynComp: a fatal error has been detected by the Java Runtime Environment.

[boyan...@gmail.com]

Hi,

I met an error when running DynComp on the Math project from defects4j. When I use the TestRunner, some of the bug ids will have the issue https://github.com/codespecs/daikon/issues/304. Some of the bug ids could be solved by Mark’s solution. However, some others will have "# A fatal error has been detected by the Java Runtime Environment:..." (detailed output is pasted at the end).

For example, for the Math-2f (Math project, bug 2, fixed version), I wrote a helper to run the specified test, 

import org.junit.Test;
public class TestIt{
    @Test
    public void testIt() throws Exception {
        org.apache.commons.math3.distribution.HypergeometricDistributionTest test = new org.apache.commons.math3.distribution.HypergeometricDistributionTest();
        test.testMath1021();
    }
}

If I only run the Test, it works well:

$ java -Xmx43G -cp /home/ubuntu/daikon-5.8.8/daikon.jar:target/classes/:target/test-classes/:/home/ubuntu/launcher/:. org.junit.runner.JUnitCore Brok

er |& tee ft_invariants_files0/dyncomp-output.txt

JUnit version 4.13.2

.

Time: 0.028

OK (1 test)

But when I run DynComp with it, it will has the fatal error of JVM as below:

$ java -Xmx43G -cp /home/ubuntu/daikon-5.8.8/daikon.jar:target/classes/:target/test-classes/:. daikon.DynComp '--ppt-select-pattern=^org\.apache\.commons\.math3\.distribution\.HypergeometricDistribution'  org.junit.runner.JUnitCore Broker 

JUnit version 4.13.2

The detailed reproducing steps are:

1. install defects4j, https://github.com/rjust/defects4j 

2. checkout the Math-2f using `defects4j checkout -p Math -v 2f -w Math2f`

3. go to Math2f and compile the project using `defects4j compile`

4. compile the helper TestIt.java  mentioned above

5. go to Math2f and run `java -Xmx43G -cp $DAIKONDIR/daikon.jar:target/classes/:target/test-classes/:<the helper's path> daikon.DynComp '--ppt-select-pattern=^org\.apache\.commons\.math3\.distribution\.HypergeometricDistribution' org.junit.runner.JUnitCore TestIt

Thank you very much for your help!

Regards,
Bo
