[OpenJDK 2D-Dev] Review request for bug 100053

Oh yes. Stupid me :-)

I followed all usages of crossings and crossingsIndices and they all end
up in endRendering(). There is a loop at the beginning of which the
arrays get initialized using setCrossingsExtends(). The problem occured
when this loop was never entered, in that case we hit
crossingListFinished() with (possibly) null arrays. There I added the
null checks and it should cover all potential NPEs on these arrays.

The updated webrev is:

Ok now?

Thanks, Roman
