I did try it before it hangs and still no thread dump.

However, messages.log contains a lot of the following exceptions:

Subject: Re: Try out and vote for Apache NetBeans 12.1

The "reflective access" warnings are not unusual.

Not being able to get a thread dump is unusual. Have you tried it
*before* it hangs to insure your process is good? You can also try 
uSoft/SysInternals Process Explorer, if you get properties on a parent, there 
is a threads tab.

Have you taken a look at messages.log?

When I run from a windows shortcut (win7) I always have

    --console new

as part of the target command, and start minimized (except for the first time, 
because it will hang asking for imports). And with the property in netbeans.conf

    -J-Dnetbeans.logger.console=true

Then all the logging... is put in a second window, you can even open this 
window while it's running to see what stuff is being generated. 
It's basically a the samestuff as messages.log but realtime without the output 
buffering.
