while migrating from Eclipse Helios to Kepler I am getting an error as below:

Hmm, weird. That would seem to indicate that you have two versions of org.eclipse.emf.common loaded. Except org.eclipse.emf.common is a singleton bundle.

My guess is that this is similar to bug 376667 which seems to have been triggered by having two active versions of org.eclipse.jface. Try running eclipse with '-clean' and see if that makes a difference.
