Mike,
I can certainly try to do that. Given how trivial the change is and the
somewhat obvious observation that Long.parseLong would avoid boxing
compared to Long.decode, I was simply pointing out a fairly easy change
that could be made in case the maintainers of this class simply haven't
looked
The easiest wat to proceed would be for you to submit a webrev patch with both
changes along with your microbenchmark test. Once the change is incorporated in
the jdk8 mainline the sustaining teams can evaluate it for backporting to jdk 7
and 6.

Alan,
Sorry I should've stated that I looked at this in detail in java 6 but only
glanced at the UUID impl in 7 just now on my phone. If String.split() has
a fast path now then forget my suggestion #1 :). Using Long.parseLong
should still be applicable though.
Thanks

Hi all,
I noticed that this method could be made a bit more performant by:
1) creating a statically initialized Pattern for "-" and then calling
split() on that. Currently the method calls name.split() which compiles
the pattern on each invocation.
