Subject [jira] Updated: (HARMONY-3314) [drlvm][threads] DRLVM hangs on exit while detaching thread
Date Sat, 28 Apr 2007 13:35:15 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3314?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ivan Popov updated HARMONY-3314:
--------------------------------

    Environment: Linux/ia32, Windows/ia32, Harmony-jdk-r514598, Harmony-jdk-r533073  (was:
Linux/ia32, Harmony-jdk-r514598)

I see this problem now often occur on Windows platform also. It blocks running EUT jdtdebug
suite because of too many hung java processes hold system resources and this make testing
almost impossible.

>             Project: Harmony
>          Issue Type: Bug
>          Components: DRLVM, JDK
>         Environment: Linux/ia32, Windows/ia32, Harmony-jdk-r514598, Harmony-jdk-r533073

> Many JDWP tests run long time on Linux because DRLVM intermittently crashed at exit.
> For example, the following test
>   org.apache.harmony.jpda.tests.jdwp.Events.VMDeathTest
> Here is typical diagnostics in the test output:
> Waiting for debuggee exit
> STDERR> SIGSEGV in VM code.
> STDERR> Stack trace:
> STDERR> 	1: ?? (??:-1)
> STDERR> addr2line: '[heap]': No such file
> Ignoring exception in ProcessWaiter thread interrupted: java.lang.InterruptedException
> # ERROR: Enforced debuggee termination
> 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.Events.VMDeathTest
> 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.Events.VMDeathTest
