JAXB issue with 6.2 Blueprint container when sharing JAXBContext across bundles

Issue

• We are migrating from 6.1 to 6.2P2 and one of our existing application which works fine on 6.1 gets some issues during deployment in 6.2.
• We can see the following log files,

• Same thing works fine in 6.1. Even though it complains about missing objectfactory or jaxb.index file, we can see objectFactory class in the same package.
• Also this works when using spring file and not with blueprint.
