However, with the OOM issue in JBoss Rules 3.0.5, we cannot really use it in enterprise environment. It would be good if we can get 3.0.6 out sooner. BTW, have your guys check in the fix? Is there anything we can help to get 3.0.6 out sooner?

You could attempt to regenerate the grammar again with latest versions of antlrworks and antlr, although I'm not sure if it works without updates to the drl. Not sure when 3.0.6 will be out, probably not for a few weeks. Mark Dejia Wang wrote: 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:[EMAIL PROTECTED] 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.
