[jdktools][jpda] JDWP test org.apache.harmony.jpda.tests.jdwp.ThreadReference.StopTest fails
with "operation timed out"
-----------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-3341
                 URL: https://issues.apache.org/jira/browse/HARMONY-3341
             Project: Harmony
          Issue Type: Bug
          Components: JDK
         Environment: Windows/ia32, Linux/ia32, Harmony-jdk-r515478
            Reporter: Ivan Popov


The following JDWP unit test

  org.apache.harmony.jpda.tests.jdwp.ThreadReference.StopTest

fails on both Windows and Linux platforms with the same diagnostics:

testStop001: get threadID to Stop...
testStop001: ID of the tested thread to Stop = 1320
STDOUT> [SYNC] Message sent: ready
testStop001: get throwable for Stop command...
testStop001: throwable = ObjectID: 2040

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
