This is a problem we've also run into on certain platforms. What are
you building on? To workaround, take a look at OMERO_HOME/hudson.sh
which performs the continuous builds. Specifically:

export JAVA_OPTS=${JAVA_OPTS:-"-Xmx600M -Djavac.maxmem=600M
-Djavadoc.maxmem=600M -XX:MaxPermSize=256m"}

are the settings we use.

Best wishes,
~Josh.
