Description Jerome Lanneluc CLA 2006-05-18 04:39:34 EDT 
3.2 RC4

Running a plain Eclipse 3.2RC4 (i.e. no WTP or other Callisto projects are installed) on a JDK 1.5.0 VM, I'm often getting OutOfMemoryErrors due to no perm gen space left.

Running the same Eclipse install under a JDK 6 VM, I took a VM thread dump, and it looks like the perm gen space is 99% full:

Heap
 def new generation   total 11392K, used 206K [0x100a0000, 0x10cf0000, 0x11450000)

No shared spaces configured.

Also note that I didn't use Ant during the session when I got the OutOfMemoryError.

It looks like I'm running into http://bugs.sun.com/bugdatabase/view_bug.do;:WuuT?bug_id=4957990.

Shouldn't we change the default MaxPermSize to 128M (i.e. -XX:MaxPermSize=128m) as we do for the MaxHeapSize ? Otherwise I suspect a lot of people using Callisto will run into this problem as you get much more class loading now.
Comment 3 John Arthorne CLA 2006-05-23 13:04:15 EDT 
Sounds like it should at least be a readme.  We have to be careful with adding -X options to eclipse.ini because they may not be supported by all VMs.

Actually looks like a dup.
