See VCM bug http://dev.eclipse.org/bugs/show_bug.cgi?id=12033

The build is a bit old, maybe you are doing better here. I've seen this same 
behaviour though - UI activation on startup is causing a lot of work to happen 
in JDT-core, and all this appears to be occuring the UI thread.

Severity 'major' was to reflect severity reported assigned to the above VCM bug.

Added reporter of VCM bug to CC of this bug.

We got many complaints when we did not persist the state of the type hierarchy. 
Users are expecting to have the workbench fully restored on start-up. Computing 
the type hierarchy isn't cheap, moving the computation in a background thread 
is not an option given that the CORE infrastructure is not thread safe.

We might want to investigate persisting hierarchies ?

Is essentially the same as 15486.
