Re: [appfuse-user] mvn jetty:run => OutOfMemoryError: PermGen space

Thu, 08 Mar 2007 14:08:28 -0800 

Ok, what i done was added the following under plugins in the POM:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <configuration>
       <jvm>${JROCKIT_HOME}/java/bin</jvm>
   </configuration>
</plugin>


JROCKIT_HOME is a windows environment variable i setup to point to the
directory containing JRockit. Just to reiterate for everyone, this means
you are only using JRockit for testing.

One thing i did notice when trying to get to the bottom of this problem
was when running the tests with Suns JVM 1.5, the java.exe process,
viewed using task manager, consistently hit about 96mb before giving an
out of memory PermGen space error. I take it this 96mb is a setting
specified somewhere but i don't know where?

Copying $JROCKIT_HOME/lib/tools.jar to
$JROCKIT_HOME/jre/lib/ext/tools.jar fixed this problem.  The reason
this happened is probably because I chose *not* to use JRockit as my
default JRE.

Maybe I spoke too soon, it looks like there's issues using JRockit
