It looks like, you upgraded to new version, didn't you ? 

I think soo too. The missing class has never been part of any NetBeans
distribution. The reporter seems to have been using a 3rd party module and now
is trying to reuse an old userdir with a new installation of NetBeans. This
installation apparently doesn't include the 3rd party module.

Deleting the ${userdir}/config/Keymaps folder should fix the problem.

Actually I installed in a brand new directory using a brand new userdir. But I
did install my NB41 settings when asked.
After downloading CollabModules and ExperimentalRefactorings and CVS-Refactoring
support module I didn't receive ClassNotFoundException anymore.

Hmm, then it does sound like a bug. Re-opening.

Hanzi, anything you can do about it?

Too late to fix in NB5.0.

It would be nice to fix this issue for NB 5.5 , 6 duplicates in 3 days ;(

ShortcutsFolder-> core team

there is no "big" problem in code. We should only decide, if this CNFException
should be written to console, or not.

Since even the stack trace is frightening (see issue #76973), I have patched it
further in the trunk to just print a one-line warning.

ShortcutsFolder.java 1.43
ShortcutsFolder66845Test.java 1.3

I received a similar error.  I had just upgraded from 4.1 to 5.0 and started 5.0
for the first time from the install-created desktop icon.  It may also be
similar to a refactoring issue posted to the list once.  Here is the stack trace
I got.

gglazer, com.xpdev.refactory is some unrelated module which you apparently have
KB shortcuts for but no such module is installed. Not relevant to this issue.

Could you open a new issue, then?

Thanks.

Re. separate issue - I already have a patch to make warnings about unloadable
shortcuts quieter. Other than that, there's not much to do - you seem to have
shortcuts for a third-party module that is not installed.

Okay, so having not poked around with the keyboard options at all, I wasn't even
aware of nb shortcuts.  I certainly didn't set them, so this was either in my
previous install or perhaps set during an update.  

That said, removing the cntl-y shortcuts from the various profiles Refactor ->
Redo made the message go away.  What confuses me about this is that there are
other shortcuts under Refactor (e.g., ExtractMethod, Rename, etc.) which have
shortcuts assigned and they do not throw this exception.
