    [junit] 	Caused an ERROR
    [junit] Java heap space
    [junit] java.lang.OutOfMemoryError: Java heap space

{noformat}

Proposed patch, add this to the junit tag:
{code:xml}<jvmarg value="-Xmx512m  -XX:PermSize=128m -XX:MaxPermSize=512m"/>{code}
or
{code:xml}
<jvmarg value="-Xmx512m"/>
<jvmarg value="-XX:PermSize=128m"/>
<jvmarg value="-XX:MaxPermSize=512m"/>
{code}
not sure which one is correct, I need to check...

See [JUnit task|http://ant.apache.org/manual/OptionalTasks/junit.html] for more details

An *even better solution* is to check why there is a OutOfMemoryError in the first place.
May be it's a sign somethings'wrong or consuming too much memory...
