Description Olivier Thomann CLA 2001-10-10 22:57:14 EDT 
Import the source from ott7f\moss:\prs\replicat\archive\phoenix\1g9tg06\VA0051_GrosseKlasse.java in a java project.
	Open this compilation unit. The CPU goes to 100% for a long time before the outliner displays the structure.

	The actual parsing time is really small. The problem comes from the display of the resulting structure.

Comment 4 Andre Weinand CLA 2002-02-27 10:21:04 EST 
The problem still exists in 20020214.

The most critical issue is that if you open the class from the package view a 
new editor tab appears immediately but no editor contents is shown and the UI 
seems to be dead for 6 seconds on my 1GHz machine.

A solution would be to show the editor contents immediately and to start 
building the outline tree from a separate (low priority) thread.

Build 20020423 improves outliner performance.
