Apple used to have a beta 1.6 JDK available, but it looks like it was
pulled from their developer site recently. I tried using the beta a
while back, and found that some apps wouldn't work with it, so it might
not be a good solution anyways.
I'm a bit confused by this discussion though. How would compiling the
jars with Java 1.5 and running on 1.6 degrade performance (assuming that
the jars don't use any new 1.6 APIs)?

Does anybody know if there is a jdk6 available for Mac? I checked the apple
developer site, and there doesn't seem to be one available, despite blogs from
last year claiming apple was distributing it.
Since I do my development work on a Mac, switching to jdk6 would be very
difficult for me if I can't find a darwin jdk6. I need to be able to build job
jars and patch hadoop.

Yes, it seems I built the 0.14.2 release using 1.6 by accident. Sorry!
If this is a blocker for folks, please file an issue in Jira and I
will make a 0.14.3 tarball that's compiled with Java 1.5 instead.
I believe the QA framework runs
the unit tests under 1.5 to ensure that we don't break 1.5 compatibility
accidently.
Yes, that is the case. Hudson uses Java 1.5.
I do think it is worth changing the requirement up to java 1.6, but of
course not as a patch release. *smile* (The performance of socket
polling is much much better under 1.6.) I would not recommend running
Hadoop under java 1.5 unless you don't have a choice.
Can you please file an issue in Jira for this? Then folks can weigh in
there.
