Dimitris Andreadis commented on JBAS-4216:
------------------------------------------

Excellent reports, thank you.

I've made the following changes:

- doubled the MaxPermSize (128m from the default 64m) on Sun-based JVMs in the all config
- increased by 50% (512m to 768m) on Sun-base VMs the MaxPermSize for the compatibility tests, that traverse and load all the classes to check the SerialVersionUIDs.

I understand that the -XX:MaxPermSize is only recognised by Sun-based VMs (e.g. HPs), but not JRockits. But then JRockits doesn't seem to have this problem anyway.

I next step would be to actual includes the max heap space in the all config from what we have now -Xmx128m, but then this will make it harder to spot real memory leaks. So I'm not changing this now.

I would expect for most memory leaks to disappear with those changes.

Another thing to be aware of, when reporting the OOMEs, it's essential to know which part of the tests produced it, since every set of tests runs potentially with a different set of setting.
