[rules-users] Fresh Guvnor Install throws ClassNotFoundException

[Michael Anstis]

Guvnor doesn't use OSGi.

The stack trace suggests the JAR you are has a dependency on OSGi:-

org.drools.guvnor.server.contenthandler.ModelContentHandler.getImportsFromJar.

The remainder of the stack trace relates to trying to load the imported
class.
