[jdktools][jpda] JDWP test org.apache.harmony.jpda.tests.jdwp.MultiSession.ListenConnectorTest
intermittently fails with connection timeout
-------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-3377
                 URL: https://issues.apache.org/jira/browse/HARMONY-3377
             Project: Harmony
          Issue Type: Bug
          Components: JDK
         Environment: Windows/ia32, Harmony-jdk-r517567
            Reporter: Ivan Popov


The following JDWP unit test

  org.apache.harmony.jpda.tests.jdwp.MultiSession.ListenConnectorTest

fails with connection timeout error on Windows platform only when it runs together with other
JDWP tests.
Rerunning it as a separate test case always pass. This test also never fail on Linux platform.

Here is typical output of the test failure:

[SYNC] Closed socket
Completed sync connection
Ignoring exception in disposing debuggee VM: java.lang.NullPointerException
Waiting for debuggee exit
Finished debuggee with exit code: 1
Waiting for redirectors
Finished debuggee VM process and closed connection

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 start all JPDA tests:
    cd working_jdktools
    export CLASSPATH=<...>/trunk/common_resources/depends/jars/junit_3.8.2/junit.jar
    ant test -Dbuild.module=jpda

3. see results in <...>/trunk/working_jdktools/build/test_report/html/index.html

Rerunning it as a separate test case leads produces correct output:

<<<=====================================

To reproduce this:

2. Run separate test case:
    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.MultiSession.ListenConnectorTest

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.MultiSession.ListenConnectorTest
