Description Jerome Lanneluc CLA 2003-11-21 07:24:26 EST 
Build 20031120

As shown in bug 47051, we reenter DeltaProcessingState.initializeRoots() in the 
same thread too many times while initializing classpath containers. The depth 
of the stack is o(n2) the number of projects in the workspace. This could 
easily cause StackOverFlowErrors.

Comment 2 Jerome Lanneluc CLA 2003-11-21 07:55:01 EST 
Changed initializeRoots() to not reenter if the same thread is already 
initializing the roots.

Starting the workbench with Resources perspective only, then switching to the 
Java perspective used to take 17s on my machine. It now takes 6s.
Comment 3 Jerome Lanneluc CLA 2003-11-21 12:14:29 EST 
Reopening as fix is not good enough: causes a NPE if opening a Java perspective 
without the Package Explorer visible. Will not go in M5.
Comment 4 Jerome Lanneluc CLA 2003-12-10 06:23:28 EST 
Added fix back and verified that there was no NPE any longer.
Comment 5 Jerome Lanneluc CLA 2003-12-11 07:16:19 EST 
Improved fix so that the 'roots' field of DeltaProcessingState are initialized 
(the NPE can no longer happen).
Comment 6 Frederic Fusier CLA 2003-12-17 07:02:12 EST 
Verified for 3.0 M6 with build I200312162000.
Comment 7 John Arthorne CLA 2004-03-08 14:11:57 EST 
Jeem is getting stack overflows in I20040304 that look just like this. See bug
53953... possible regression?
