Description Jerome Lanneluc CLA 2002-10-15 07:05:59 EDT 
Build 20021009

1. Import org.eclipse.core.boot as binary project
2. Turn Java delta tracing on
3. Import org.eclipse.core.boot as source project
Observe: You get the following delta (there is no indication that boot.jar was 
removed from the classpath)

Comment 1 Philipe Mulet CLA 2002-10-15 11:00:04 EDT 
Sounds like a must fix.
Comment 2 Jerome Lanneluc CLA 2002-10-18 11:17:12 EDT 
Fixed by remembering the old package fragments roots in the delta processor 
when a project is deleted. The SetClasspathOperation uses these roots to 
compute the delta.
Comment 3 David Audel CLA 2002-11-13 06:57:00 EST 
Verified.
