[jboss-jira] [JBoss JIRA] (DROOLS-1198) NoClassDefFoundError when using str[endsWith] on a field that matches an imported class name

NoClassDefFoundError when using str[endsWith] on a field that matches an imported class name -------------------------------------------------------------------------------------------- Key: DROOLS-1198 URL: https://issues.jboss.org/browse/DROOLS-1198 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.4.0.Final Reporter: Chris Austin Assignee: Mario Fusco Priority: Minor Attachments: DROOLS-1198-unabletoreproduce.zip, screenshot-Mac.png This error was triggered when accessing the user field with str[endsWith] when user is null: java.lang.NoClassDefFoundError: mssp/io/model/user (wrong name: mssp/io/model/User) Condition that triggers the error: $a : Alert(user!=null, user str[endsWith] "$") This does not trigger the error: $a : Alert(user!=null, user matches ".+\\$") If I remove the import for the User class the error will not be triggered. As a workaround I've switched to using matches instead of str[endsWith], but I'd prefer to switch back. I did not experience this issue in 6.3.0-Final, so it appears to be a regression in 6.4.0-Final
