Root path of kjar module is incorrectly calculated under Windows for both spring and blueprint integration ---------------------------------------------------------------------------------------------------------- Key: DROOLS-1294 URL: https://issues.jboss.org/browse/DROOLS-1294 Project: Drools Issue Type: Bug Components: integration Reporter: Mario Fusco Assignee: Mario Fusco KModule post processor wherein createKieModule method implementation removes the drive name from the base directory url which causes the problem. So if we have base jetty temp dir path like C:\users\user\tem\jettytempfolder\webapp\web-inf\classes the below lines of code removes the "C:\" from the url which makes it invalid path and which in turn isnt recognized as classes file folder.
