> Test description:
>   Start a lot of threads.
>   All of them run the following:
>     - load a class which implemens interface with more than 500 superinterfaces;
>     - verify fields values of this classes;
>   This verification is repeated several times.
> Harmony crashes during test running but not always. It happens on average in 10% of runs. So it is better to run test in cycle.
> Steps for reproducing:
> Unzip attached file. It contains sources and classes of test.
> If you like to re-compile test, use command in cygwin:
> $ find dir -name "*.java"|xargs javac
> where dir - is a directory of test (org e.g.)
> To run test in cycle use command:
> $ gg=104; r=0; while (($gg == 104)); do (./java -Dorg.apache.harmony.test.share.stress.ReliabilityRunner.params="org.apache.harmony.test.stress.classloader.NotSynchThreads.SupIntf.testManySupIntf1{}" -classpath "./;./junit.jar;" org.apache.harmony.test.share.stress.ReliabilityRunner;); let "gg = $?"; let "r += 1"; echo $r; echo $gg; done
> where ./java - is a tested jvm (harmony), ./junit.jar; - is a full path to the junit.jar
