Description Jaroslav Tulach 2010-04-12 06:53:43 UTC 
I am sure this has already been reported many times, but I am not able to edit any larger java file in today's build. For example try openide.util/**/RequestProcessor.java, I can type one character per second (at most, often not even that). This renders the whole IDE unusable. 

I am attaching few seconds snapshot in a nps file. The CPU however stays at 100% for minutes. By looking at the nps file, I'd bet there is a little bit too much activity in editor painting.

The ARQ is busy by expensive unregistration of dead listeners
Comment 5 Miloslav Metelka 2010-04-13 15:06:32 UTC 
IMO this is rather P2. There are computations of TextLayout instances which is logical for ongoing modifications. The total count should be decreased once issue #183646 gets resolved.
The rest seems to be related to parsing so reassigning.
Comment 6 Tomas Zezula 2010-04-13 15:16:12 UTC 
I will look at at.
Comment 7 Jaroslav Tulach 2010-04-13 18:09:24 UTC 
I made the bug P1, as the Monday build was unreleasable to public, even as beta. As the linewrap is supposed to be disabled in the beta branch, I no longer insist on the priority. P2 is fine.

Fixed in jet-main: d04c24201ca0 e00134af07b3
The ClassIndexManager case is fixed.
