http://www.netbeans.org/issues/show_bug.cgi?id=129227 describes the bug.
I didn't mess with moving things around, I simply did this:
Alternative (non-destructive) workaround.
Edit the file /Applications/NetBeans/NetBeans\ 6.1\ Beta.app/Contents/Resources/NetBeans/etc/netbeans.conf
add "-J-Djava.ext.dirs=/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/lib/ext/" to the definition of "netbeans_default_options".
and that's it, restart netbeans and it works. mofo's
Here's the stack trace produced before the fix:

Great post, Jonathan. My NetBeans has been broken for a few days, I've been going mad trying to fix it. I'd not made the connection with installing the new JDK. When I found your post I was able to fix the problem.
Thanks for the comment. There is nothing more frustrating then upgrading one thing just to break something else.
Worked for me too! Thanks Jonathan. This was a really frustrating bug.
Just downloaded netbeans for my new Mac and couldn't create a simple class file. Netbeans does have this issue in their issueZilla and they believe it is the new Apple JDK.
Thanks for the tip, it works great!
This is a year later and Apple have broken 1.5 again. Because 1.6 is available on dual core intel I changed these lines:
#netbeans_jdkhome=/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home
netbeans_jdkhome=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
Seems to work.
Thanks for the post
I appreciate the information. Java is one of the consistent player from the development industry which has been providing the wider scope for developers to come out with different solutions.
