Laszlo Kishalmi commented on NETBEANS-1419:
-------------------------------------------
Well, this issue might be there in a long time. Though releases usually
suppress assertions. And changing the JDK throughout the PopUp menu is quite
unusual use case. My proposal fixing this issue would be remove the PopUp Menu
for Edit JDK from the Ant Projects. Project Customizer is a much better place
to do that.
The reason for the assertion: the action is opened out of the AWT thread as it
was previously marked as async, so NB runtime put the Action execution to a RP
thread out of AWT.
