Description Eric Jodet CLA 2007-04-17 08:42:41 EDT 
(if incorrect product / component, please move accordingly) 

Version: 3.3.0
Build id: I20070323-1616
sun jre 1.6.0_02-ea

scenario: installed Europa on top 3.3 M6 (all features installed, except the 3 referenced by bugs 182703, 182548, 182549 and 182550.
- after install, restart the workbench against a previous 110 + projects workspace I had: the MyLar automatic preferences page shows-up.
- click Finish

-> 1- in the Progress View, the Java Tooling initialization sounds like stucked at 2% (to be attached screen shot)

-> 2- java.exe process takes 100% of the CPU

-> 3- unable to quit properly as unable to save the workspace

Took jvm and yourkit snapshots (to be attached): hot spot seems to be org.eclipse.osgi.internal.module.GroupingChecker.isConsistentInternal(ResolverBundle, ResolverBundle, ArrayList, boolean) (The method calls itself recursively)

which is called by:
org.eclipse.pde.internal.core.MinimalState.resolveState(boolean)

This is currently preventing me from using europa against a previous workspace I had.

Comment 4 Thomas Watson CLA 2007-04-17 09:02:00 EDT 
This is a dup of 181327.  TPTP is using some downlevel orbit bundles which contain Export-Package "uses" clauses.  This surfaced a critical performance issue in the resolver.
