With 6.0 M4 a deploying of our application is not possible. It occur the follow error. With 6.0 M1 is has work.

The cause of the problem is that in the war file are multiple jar files with different versions of a utils package. Only one of this package is needed. It seems that the ClassLoader will load all versions of the same package. This produce the problem.

If you need to preload of all classes (also many which never needed) then you should you create only a warning if a single class can not loaded.
