> The problem is that JVMTI function StopThread() does not throw specified exception in
a waiting thread, until waiting timeout is expired.
> To reproduce this failure:
> 1. create Harmony JDK with federated build:
>     svn checkout https://svn.apache.org/repos/asf/harmony/enhanced/trunk
>     cd trunk
>     ant
> 2. goto jdktools directory, add junit to classpath, and run particular test:
>     cd working_jdktools
>     export CLASSPATH=<...>/trunk/common_resources/depends/jars/junit_3.8.2/junit.jar
>     ant test -Dbuild.module=jpda -Dtest.case=org.apache.harmony.jpda.tests.jdwp.ThreadReference.StopTest
> 3. see results in <...>/trunk/working_jdktools/build/test_report/html/index.html
> It is possible also to run test directly from command line:
>    cd working_jdktools
>    deploy/jdk/bin/java -classpath ../common_resources/depends/jars/junit_3.8.2/junit.jar:build/tests/classes
\
>    org.apache.harmony.jpda.tests.jdwp.ThreadReference.StopTest
