At this point I expect that Sun will release Java 7 before Apple ever
release Java 6 on OS X, and I'm not holding my breath that Apple ever
will release Java 6 (they've been teasing us for far too long).
Setting pessimism aside, I've had a release of Java 6 running on my G4
under OS 10.4 (Tiger), so I hope they would release at least some
version of Java 6 for PPC. This was almost certainly 32-bit.
At Java One 2007 at one presentation I saw, Sun acknowledged that there
is a performance hit to using 64-bit Java (related to 64-pointers). They
were working on a different pointer handling scheme to eliminate the
performance hit, so it may not be available until Java 7. I'm not sure
about how Apple feels about 64-bit Java applications running slower than
32-bit ones, given all the praise they've had for the 64-bit performance
of Leopard. I thought the message was that Leopard runs 64-bit
applications even on 32-bit hardware?
I really wish Apple would replace Catbert as the head of Apple's Java
Strategy.
Cheers, Eric

Subject: Re: Will Java SE6 have 32-bit version?
we can only hope. Technically we not really meant to discuss such none
technical issues, but hell I don't care.
Apple have stated before that there will be no PPC64 Java 6 vm, but I
can't see them not supporting 32-bit Intel. What worries me is whether
or not the Apple Java team will be given the resources in order to
ship the Java 6 VM anytime soon.
Your options are limited:
- just keep waiting (boring)
- install soylatte (not quite 100% ready, but v.impressive)
- buy a new mac (expensive)
- install linux (not really the point of owning a mac )
