Description Jan Lahoda 2004-03-29 16:35:38 UTC 
NB3.6, 200403251830, with the debugger patch for
#41314. JDK1.4.2_03.

1. Start the debugging for
examples.advanced.MemoryView (comes with the test
applications for debugger, see
http://debugger.netbeans.org).
2. Create a breakpoint at line 98.
3. Open the Classes view.
4. Go into the Classes view.
5. Select examples.advanced.MemoryView
6. Right-Click and choose Tools/Override methods
7. A dialog is opened and the first attached
NullPointerException is thrown.
8. Close the dialog, select
examples.advanced.MemoryView.MemoryView$1.
9. Right-Click and choose Tools/Override methods
10. A dialog is opened (no NPE). Select some
methods and click OK.
11. The second attached NullPointerException is
thrown.

I guess that the debugger tries to filter out
actions from the class node, but forgets for the
Tools/Override methods (and Tools/JUnit Tests
which are there two).

Comment 5 Martin Matula 2004-07-28 13:22:47 UTC 
What's the state of this issue? Is it (going to be) fixed in debugger?
Jan's comments do not make any sense to me, sorry.
Comment 6 Jan Jancura 2004-07-28 14:01:15 UTC 
this piece of code has been removed - fixed in trunk.
Comment 7 Quality Engineering 2010-04-29 09:17:12 UTC
