       Compile the sample app. Run it using a javaagent attached.

       I found loading a script using either javaagent or bmsubmit tool causes the JVM to have a fatal error and exit. The script defines two rules with an identical rule name.

       The cause is purely a user error but should not necessarily cause the JVM stop.
