The following JDWP unit test

at java.lang.reflect.VMReflection.invokeMethod(VMReflection.java)

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.ClassType.InvokeMethod002Test

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
\
