Patch: FYI: fix PR 25389

[Tom Tromey]

I'm checking this in to Classpath and libgcj 4.1 and trunk.

This fixes PR 25389, which was discovered by OO.o.  We were throwing
an NPE when we saw a non-hierarchical URI in the File constructor.
Instead we should be throwing an IllegalArgumentException.

I've updated the Mauve test to reflect this.
