PermGen settings not taking effect

I'm trying to increase the amount of PermGen space my application has to avoid some PermGen errors.

I've tried exporting both JAVA_OPTS and MAVEN_OPTS as 

-Xms1024m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=2048m -XX:+CMSClassUnloadingEnabled  -XX:+CMSPermGenSweepingEnabled

But jconsole still shows the "CMS Perm Gen" maximum to be:

Max: 83,968 kbytes

and the application still runs out of PermGen space when it hits this.

Solution

  • have you tried adding those options to your pom - under the surefire plugin configuration as you have to tell surefire about these opts explicitly

    <argLine>-Xms1024m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=2048m -XX:+CMSClassUnloadingEnabled</argLine>
