What I did was to copy an existing class then editing it to convert it into an interface that the existing one was going to implement.
The editor then hung and the cpu went to 99% on one core and after a couple of minutes I ended up killing the process.
In the log I could see there were reported problems with FoldManager and HtmlRenderer at the time of the crash.

Could you please take and attach thread dump while you run into this? Thanks.

Thread dump of NetBeans 6.9 whilst locked
Ok here's a thread dump as I've managed to get it to hang again.
This time it was while creating a new class and running auto import
This is strange. The thread dump shows that the only thread with some activity is AWT-EventQueue-1, but it's not blocked. At the time of taking the threaddump it was rendering the editor error stripe. No other threads seem to do anything. In the log file there is an exception from maven, but it's probably unrelated. Could you please generate more threaddumps (eg. several consecutive dumps in approx 1s succession)? Thanks
Up until that last thread dump it was happening every few days, however it's not done it since - although it has had several real go-slows which I thought was the same, but it then recovered.
I had a look at the dump myself and couldn't see anything either. If it happens again then I'll do another dump.
One thing I have observed however, you mentioned maven - I use maven exclusively and a lot of the go-slows do happen just after a maven build. Some of my maven builds are pretty big so that may not necessarily be unrelated after all.
