[rules-dev] Some tips for any developers on Snow Leopard (OS-X)

I recently upgrade to Snow Leopard, mostly it was an excuse to clean
out my home directory, as I had long since lost track of where and
what was on my PATH etc...

So with a fresh install, there are a few traps with Java:

1) Java 6, 64 bit only
- you can copy Java5 from Leopard over if you really need it (I have
found I am ok)
2) GWT won't work in 64 bit or java 6:
- you can start up with -d32 to make the JVM run 32 bit, and then I
have a hacked up gwt-dev-mac.jar (ping me if you need it).
3) Java 6 uses more memory, and can feel a bit slower:
-  -XX:+UseCompressedOops - that can help when in 64 bit (if heap < 32 gig !).
