This is good news. Thanks very much, Mark
and Edson! BTW, when will 3.0.6 release be out?

I believe this was a bug in antlr that is now
fixed. I'll see if we can get a 3.0.6 release done some time updated to the
latest antlr. Edson knows more about this, as it was a bug he investigated.

Hi All,
I ran into OOM (Out of Memory) issue of JBoss Rule Engine deployed on IBM WAS 6.0.2.7. Below is the log
…

It looks like it loaded the same class hundreds of
times until it exhausts the memory.
Any idea why this happens and how to fix this?
Thanks- Dejia
