Maxim Areshkau commented on JBIDE-2674:
---------------------------------------

I tried reproduce on MAC OS too, and it's not reproducible for me.
By my opinion it's can be caused by using old eclipse workspace and it's can be resolved by cleaning workspace or by creating new workspace and importing into it projects from old workspace.
