Revert "j3dutils: add workaround for appcontext bug in Java 7 u25"1.6.0-pre111.6.0-pre10

This reverts commit 14206478b7a5bf628b59094c92d5727291c7c2bf. The fixup
has been moved into the core pipeline code.  The parts of the above commit
removing a println and adjusting the max wait time have been preserved.
