Bluecove is working for me on Snow Leopard with a 64 bit JVM.
I just added the x86_64 arch to the xcode project (although I did need the
patch I
attached to bug 95 for an unrelated issue) and Snow Leopard seems to have
done the rest.
Given that Snow Leopard has fixed this problem, I'd be interested in seeing
the next
released jar contain a mac native library built to also support 64 bit.
The one complication would be making sure the it wasn't loaded on 10.5 with
a 64 bit
JVM. I've seen some pretty wild behavior when trying to use that combo,
including
machines hard freezing temporarily after the failed attempt to read the
local address
(yikes!). So blacklisting that combo from loading the native library might
be in order.
