Getting "Unable to load a selector [/NonDraft.drl]" when try to build package using custom selector in Guvnor

Issue

• When we try to use Custom Selector with provided jboss-brms.war/WEB-INF/classes/selectors.properties file in guvnor I don’t get the defined value in the drop down.
• Exception in the serve log file:

org.drools.guvnor.server.selector.RuleBasedSelector <init>
SEVERE: Unable to load rule base.
org.drools.CheckedDroolsException: There were errors in the rule source: Unable to Analyse Expression statusDescription != "Draft":
