[rules-users] Simple rule worked in 4.0.7 and failed in 5.0.1

I ran into some problems where a fairly simple rule fails in 5.0.1 and worked in 4.0.7. I have created an issue on JIRA https://jira.jboss.org/jira/browse/JBRULES-2136 and was wondering if someone else has come across that same type of problem. The rule is: package org.drools.rules.test import org.drools.rules.test.SimpleStringType rule "SimpleKeywordTest" dialect "java" when $_theFact : SimpleStringType( stringValue matches ".*\s(ADDR)\s.*|(ADDR)\s.*|.*\s(ADDR)" ) then $_theFact.setValid(false); end Whenever the stringValue contains something like 'MY ADDR' the rule should fire but it doesn't in 5.0.1 Corneil
