install locations for OpenJDK 7...

[Mike Swingler]

Even if JDK 7 can be introduced into the Mac OS X Java version system, Eclipse will still have to modify their launcher to use it. Last I recall, they were still hard coding paths into /System/Library/Frameworks/JavaVM.framework/...

I can't say it enough - to get the "best" $JAVA_HOME on the Mac, use:
% /usr/libexec/java_home

It takes version and architecture requirements as command line parameters - check it out.
