As a warning, NetBeans is so untested with anything but the Oracle-produced JDK binaries
that it doesn't even seem to play well with OpenJDK:

http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=681
http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=691

which is supposed to be mostly the same code.

The first thing to try is to see if it will run with a Classpath-based VM such as gij,
JamVM or CACAO.  It'll be slow, but that will tell you what kind of issues you're going
to hit.

As Andrew implies though, not for the faint-hearted.
