The problem of
still persists. If you rebuild an ear after changing dependency versions, the new dependencies are included along with the old ones, leading to an inconsistent ear. The attached Maven project shows this behaviour. It was first build with "install", where log4j was in version 1.2.8. After changing the version to 1.2.17, the project was "installed" again, leading to an ear that contains both log4j versions simultaneously.
