We are running Elastic Bamboo 4.4-i386 on Amazon 2014.09. As Clover finishes building we get the following PermGen Out of Memory error:

We are running Maven 3.0.2. In the Maven job definition I have reconfigured both MAVEN_OPTS and JAVA_OPTS to provide more PermGen memory with the following commands in the job plan:
MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=768m" JAVA_HOME="/mnt/bamboo-ebs/jdk1.7.0" M2_HOME="/opt/maven-3.0.2" M2="/opt/maven-3.0.2/bin" JAVA_OPTS="-Xmx512m -XX:MaxPermSize=768m"
We were successfully compiling and running Clover as recently as a week ago with the default PermGen value of 128 MB, about one-sixth what I have configured now. After the PermGen failures began I increased the PermGen values several times.
I checked the Elastic Bamboo instance while it was actually running. I see my settings running in the processes which eventually fail out for lack of memory. The increase PermGen values are visible in the Maven/Java processes.
What could be generating the PermGen Out of Memory error?
