assertion error.

Comment 2 Martin Entlicher 2005-08-26 14:32:22 UTC 
I do not think this is a debugger problem. The actions work fine for me in older
build with up-to-date debugger.
Moving to java for evaluation...
Comment 3 Pavel Flaska 2005-08-26 15:07:37 UTC 
These actions are considered as 'background scan sensitive'. You have started
debugger before background scan was finished. 

Details at http://java.netbeans.org/ui/waitscanfinished.html

Assertion is caused by calling JavaMetamodel.invokeAfterScanFinished() outside
of AWT EventQueue. See method javadoc.
Comment 4 Martin Entlicher 2005-08-26 17:01:38 UTC 
Finally reproduced. When the debugger is started via "Debug Project" or "Debug
File" then all works O.K. Only when one needs to start debugging via "Step
Into", or "Run To Cursor", etc. it fails with the assersion error.
It's broken due to threading changes after the fix of issue #61542.
Comment 5 Martin Entlicher 2005-08-26 17:02:42 UTC 
Thanks for the comments about background scanning.
Comment 6 Martin Entlicher 2005-08-26 18:23:46 UTC 
Fixed in trunk. It's assured that J2SE actions are invoked on AWT thread:
