Hi Casimiro,

  
I've got the following problem with eclipse after update to F13: upon launch it
freezes at initial banner & uses about 80% of CPU time.
    
Please file a bug at bugzilla.redhat.com and we can work through it there.

Thanks,

Andrew
  
Hello,

Apparently I have the problem solved. First of all, the listing had all that modules because when eclipse refused to start I assumed something was lacking and behave just like a n00b (yum install "eclipse-*" kind of thing). So, it happened prior of having all those modules installed. Anyways, what I did was to uninstall eclipse & everything related, to remove .eclipse and workspace (inherited from F12), re-install eclipse and bring back old content. And it worked.

Apparently it was a problem with what was before & what was updated. As error cannot be reproduced there's little sense in filling a bug.
yes there is a reason to file the bug report. The upgrade should have been seamless. Something like this has happened to many people on many eclipse updates. Maybe there is something in your scenario that would give the maintainer a clue. At worst, the bug will be closed as insufficient information.
