PermGen space Exception in Eclipse

Well a quick post. Sometimes Eclipse really go nuts and starts throwing this exception for each and every action :

Unhandled event loop exception
PermGen space

You can solve this by editing the eclipse.ini file which is residing in the same directory as the eclipse.exe. Towards the end of the file add this line :


You can give whatever space you like such as 256M or 512M. After this restart your eclipse and forget about the PermGen Space Exception. (I Hope So. :P)

For those who are more interested in permGen, The permanent generation (or permgen) was used for class definitions and associated metadata prior to Java 8. Permanent generation was not part of the heap. The permanent generation was removed from Java 8. Originally there was no permanent generation, and objects and classes were stored together in the same area. But as class unloading occurs much more rarely than objects are collected, moving class structures to a specific area allowed significant performance improvements. In short, PermGen is used by the JVM to hold loaded classes.
