OutOfMemoryError: PermGen space

I encountered this error with Tomcat 5.5 and in Eclipse as well when using Web Tools features. Adding the following JVM options resolved the problem:

-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:MaxPermSize=256M

Of course, you can use a different value for the MaxPermSize depending upon the available RAM.

For Eclipse, I added these options to the shortcut:

C:\programs\eclipse\eclipse.exe -vmargs -Xmx768M -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:MaxPermSize=256M

For Tomcat, I edited catalina.bat to add the following line:

set JAVA_OPTS=%JAVA_OPTS% -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -XX:MaxPermSize=256M
