[jboss-jira] [JBoss JIRA] Closed: (JBRULES-783) NoViableAltException when parsing eval rules

[Edson Tirelli (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-783?page=all ]

Edson Tirelli closed JBRULES-783.
---------------------------------

    Fix Version/s:  4.0.0.MR3
       Resolution: Done

Not possible to reproduce the problem in current trunk revision #12384.

As we did a major grammar rewrite, I guess the problem was solved during the rewrite. 

Added unit test anyway to avoid any possible regression.

Thanks for reporting and providing the test case.
