When importing the ws bundles, Eclipse complains that there is a build dependency between the ws.core (ws.core-tiger) and ws.support.
It appears that the ws.core bundle declares in its imported packages:
Those packages are also found in the ws.support, hence the dependency.
I don't think this will prevent the classes being resolved at runtime since there is no duplicated class, but i think the imported package set in the ws.core bundle should be cleaned up by removing all the org.springframework.ws.* packages as they are declared in the exported package set.
