java.lang.OutOfMemoryError: PermGen space Exception

Question

I am getting this java.lang.OutOfMemoryError: PermGen space Exception. I am using Eclipse Juno and Tomcat 7.0. This Exception occurs at least once in every 10-1

Answer 1

It is easy to configure Java for more PermGenSpace but I would recommend to migrate to Java 1.8 runtime instead. Install Java 8 SDK and add two lines like

-vm
D:/jdk8/jre/bin/javaw.exe

to eclipse.ini. This problem is fixed starting from Java 1.8 and does not longer require any hacks.
