The error message you reported means that MVEL could not properly parse this expression: ".*@" + blacklistItemValue + ".*" What is obviously strange, but that is what the error message says. Quick try is: download and replace the mvel jar you have (should be mvel version 2.0.10) by the newest one from here (2.0.15): http://mvel.codehaus.org/Downloading+MVEL I did not tested the new mvel for regressions, but you might get lucky. Otherwise, please open a jira against Drools adding your test case and we will make sure it gets fixed and updated.

Ok, thanks for checking. I just opened a ticket: http://jira.codehaus.org/browse/MVEL-200 Meanwhile, what I can suggest is a workaround, adding a helper method to the BlacklistItemDRL that returns the pattern ready for use: onBlackList : ArrayList( size > 0 ) from collect( BlacklistItemDRL( blacklistItemType matches "MAIL_DOMAIN", customer.currentContactInformation.partyEmailAddress.email matches blacklistItemValuePattern ) from blackList.getItems()) As soon as MVEL is fixed, should be just a matter of updating the jar.
