Description Petr Dvorak 2008-04-15 09:52:33 UTC 
Build: NetBeans IDE Dev (Build 200804110003)
VM: Java HotSpot(TM) Client VM, 10.0-b19, Java(TM) SE Runtime Environment, 1.6.0_05-b12
OS: Linux, 2.6.22-14-generic, i386

User comments: I have opened Hg versioned project (NB Plugin) and I opened an XML file in the editor. Then I invoked a
Copy action in the XML code and when I pressed Enter in order to make some space for the Paste action, this exception
was thrown.

Comment 1 Samaresh Panda 2008-04-16 16:43:40 UTC 
6.1 is almost out, hence this will go into some later release post 6.1.
Fixed: http://hg.netbeans.org/main/rev/0c4d2e2f519c.
Comment 2 Petr Dvorak 2008-05-13 13:17:04 UTC 
Not reproducible + reviewed the source code (there is no cast, instanceof is used instead) -> verified
Comment 3 Exceptions Reporter 2008-10-10 16:26:33 UTC 
Reopening - reproduced in NetBeans IDE 6.1 (Build 200807020101)
http://statistics.netbeans.org/exceptions/detail.do?id=126287
Comment 4 Samaresh Panda 2008-10-10 16:38:25 UTC 
The fix was made in 6.5 so it can only be verified in 6.5.
Comment 5 Petr Dvorak 2008-11-18 15:18:08 UTC 
Verified, incorrectly reopened by "exceptions_reporter".
