Re: [rules-users] Out of Memory Issue of JBoss Engine deployed onIBMWAS 6.0.2.7

BTW, I noticed that current stable version of antlr is 2.7.7 (released November 1, 2006). Rule 3.0.5 has 2.7.6. Edson, will antlr 2.7.7 work?

Thanks very much, Mark and Edson! BTW, when will 3.0.6 release be out? - Dejia ------------------------------------------------------------------------ *From:* Mark Proctor [mailto:mproctor@codehaus.org] *Sent:* Monday, January 15, 2007 4:33 PM *To:* Rules Users List *Subject:* Re: [rules-users] Out of Memory Issue of JBoss Engine deployed onIBMWAS 6.0.2.7 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.

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?
