Description
I am doing deploy/undeploy experimental work on SAP. The test scenario
is that portal application is unloaded and redeployed repeatly on SAP's
web application server (WAS). After a few times, perm gen OOMed.
The OOM in perm gen happened with both tiger fcs and mustang b24.

The perm gen size is set to 128m, the maximal perm gen size is set to 256m.

the sequence of test steps is:
1. start SAP
2. deploy and start portal on SAP's J2EE engine
3. stop and undeploy portal
4. repeat step 2 and 3.

After 4 or 5 iterations, the test fails with an OOM.

The OOM does not go away with -XX:TypeProfileWidth=0.

Note:
SAP WAS is 64 bits kernel. it only works with 64 bits JVM.
