This is not correct. The heap space and permGen space are separate.
To increase your PermGen space use the -XX:MaxPermSize option. Example:
From research after getting the same error consistently in Eclipse 3.2 some time back it seems that excessive use of String.intern() can cause this condition. I don't know of a servlet container or JSP compiler that's guilty of that (which doesn't mean they don't exist, there must be many I've never even heard of), but if you use String.intern() in your own web application you may want to think hard about whether you really need to use it.

I believe, PermGen is a JVM's garbage collector managed generation and it is not allocated by your java application, whereas latter is allocated by your application.
This might give you the overview.

I have also came across the similar reading that it happens when unreferenced/orphan interned string are not garbage collected.
