Description Jan Lahoda 2004-07-21 20:07:13 UTC 
NB trunk continous build 20040721-1416, JDK1.4.2_05.

See the attached thread dump (look at the AWT
Dispatch Thread). The potential problem is that
the tooltip creation runs in the AWT Dispatch
Thread, so it is possible that the whole IDE is
blocked (as in the case shown in the FTD).

Comment 2 Miloslav Metelka 2004-07-22 16:25:14 UTC 
The editor is requesting EditorCookie from the java data object to ask
it for the document and line set to later attach tooltip annotations
to it. IMO this should work in a MDR-transaction free way but
apparently it does not.
After looking to the sources the JavaDataObject.getCookie() acquires
MDR transaction under certain conditions regardless what cookie is
being retrieved which is IMHO too strong. I assume that this was
changed due to certain deadlock fixing but IMO it should be revised
and things like e.g. LineCookie.getLineSet() should not require MDR
transaction. Reassigning to java for evaluation.
