Clicking the "Open a Type in the Editor" button yielded the following NPE in my
host (20011211 plus latest jdt-ui plugin):

the case sensitivity changes were not released into the integration build.
Dani pls confirm

Yes, added after 20011211.

Please confirm the test case.
The log looks as if "Search" has been pressed.
It is not possible to open (or have open) the Search dialog in combination with 
"Open a Type in the Rditor" action.

Can't reproduce with code checked in HEAD.
Please provide a test case with the steps.

Ah - found the problem: setItems triggers a modify event under Linux while it 
does not under Windows. Protected code against this now and filed a reminder 
report against platform-ui to ask if this is ok.
