Public bug reported: Whenever I run Netbeans 11 (using either openjdk11) and (eg):
1. Open Tools / Plugins. 2. Go to Settings. 3. Click on 'Add'. 4. Click 'Cancel'. then gnome-shell freezes (except for the mouse), apparently indefinitely (I have left it for 30+ minutes.) I can login as another user via CTRL-ALT-F1 and kill the frozen session using loginctl. Sometimes this kills gnome-shell completely and I have to power cycle; other times I can switch back to the login with CTRL- ALT-F1 and continue. This also usually happens when I close any other popup windows in Netbeans. I have tried making the popup windows modal and non-modal, but it makes no difference.
