This is good news. 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.
