Remove label from code (#1894)

This removed some comment/code fragment which happens to be valid Java syntax, but doesn't look like it really belongs here.

Add OSGi support for PMML (#1819)

* Generate OSGi metadata for drool-pmml and kie-pmml

* Fix class loader issues for OSGi

This change fixes a few class loader issues which manifest when using

OSGi. The changes explicitly use the correct classloader instead of

relying on the context class loader.
