jogl: fix two impossible comparisons in glu/tessellator

The comparison to Long.MAX_VALUE will never trigger as it is coparing with an int.
The intent of this code appears to be to check against Integer.MAX_VALUE which is
used as an error code (unable to allocate sufficiently large array) from the
priorityQueue.

jogl: avoid creating a second String object, one is enough

One String is already being built, passing it to new String() is just wasteful as
the temp String can be returned just as easily.

jogl: allow short-circuited comparison in comparison

For this case && and & work equivalently, but using && allows the second comparison
to be omitted if the first comparison is false.  Likely just a typo.
