Subject [jira] Commented: (OPENJPA-737) Unit tests fail with OutOfMemoryException during build on Playstation 3
Date Fri, 03 Oct 2008 17:24:44 GMT


Kevin Sutter commented on OPENJPA-737:

Do your kids know that you are hijacking their machine for your development environment? 

Are you running with the IBM JDK or the Sun JDK?  If you are running with the IBM JDK, you
may  be hitting the issue I was having with the maven Release plugin.  Here's what I put out
on our Release page (

o  If using IBM JDK, then also set the system property test.jvm.arguments to -Xdump:none (Avoids
OOM heap dumps on selected tests. These extra files throw off the rat:check processing.) For

     mvn -Dtest.jvm.arguments="-Xdump:none" ...

Or, you could switch to the Sun JDK...

Let us know if this was the cause of your problem.  OpenJPA has a testcase that forces OOM
errors, so you just might be experiencing this situation.

>          Components: build / infrastructure

> The OpenJPA build fails with an OutOfMemoryException on Playstation 3 while running unit
tests.   I end up with a large core dump and other debug files.   The build is successful
when I disable the unit tests.  Is there a way to run the build+unit tests on machines with
limited memory (256mb core)?  
> BTW, I have yet to get an OutOfMemoryException or javacore from Metal Gear Solid.  An
OpenJPA build should be a piece of cake.  :-) :-)
