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.</span></font></p>

<p class="MsoNormal"><font color="black" face="Times New Roman" size="3"><span style="font-size: 12pt;">Antlr 2.7.7 is just for the StringTemplate
stuff, we are actually using Antlr 3. 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.<br>

<p class="MsoNormal"><font color="black" face="Times New Roman" size="3"><span style="font-size: 12pt;">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.<br>
