Removing libmawt.so* from java-sun-jre requires list should to the
trick, and it won't brake anything as -jre provides the library anyways.

But I think the proper way to solve this would be to teach rpm/poldek to
remove all the Requires which are provided by the same package before
starting sort procedure. Alternatively, do it at the sort time - start
looking for the provided dependancy in the package that requires it.
Or would it brake something ?
