Maven project demonstrating the issue

Description of problem:
Environment: Drools 6.0.0.CR3

When using a KieScanner along with fireUntilHalt, we get an exception in thread when we change the version of the JAR file in the Maven rule repository.  
This exception is raised when 1 DRL file is removed from the new JAR in comparison with the previous version of that JAR. The problem doesn’t occur when a rule is removed from an existing .drl.
If we modify the Maven rule repository manually (typically by tampering the maven-metadata-local.xml file), the scanner triggers as expected and we also get the same exception as we were doing the deployment by Java code.
