OSGi Constraint violation error for package 'org.drools.marshalling'

org.drools.marshalling package is exported by Knowledge API(knowledge-api-5.4.0.Final.jar) & Drools :: Core(drools-core-5.4.0.Final.jar) bundles. This throws constraint violation error while starting drools-core bundle. I assume this may be error in drools-code's MANIFEST.MF file, since it doesn't have any classes under org.drools.marshalling package.

Please find the detailed error below,
