> I am having problems with with class visibility between osgi bundles when using camel 2.12 and 2.13-SNAPSHOT. I have created a showcase to reproduce the problem based on camel example projects. I have tested the created solution in camel 2.10 and problem does not exist.
> I have created a sample application which is able to reproduce the problem. Please pick it up from my forked repo:
> https://github.com/andrzej-majewski/camel/tree/MvelExpression-class-visibility
> The problem occurs when
> - camel-example-osgi-domain - project containing only domain classes required by different osgi projects ex.( org.apache.camel.example.osgi.domain.MyPojo )
> - camel-example-osgi-mvel - example project which has dependency on camel-example-osgi-domain
> Now camel-example-osgi-mvel has following camel context.
