--------------------------------------------------------------
I am using the actual RFTools Version and the actual Eclipse (Galileo) and get sporadically failures within my gui which is really annoying:

Sporadically, I cannot select any items of my taskbar when eclipse is running and there are other strange bugs when running eclipse, such as not viewing sub-menus.

After making an update to the actual rf-plugins, I get this error which prevents me from opening eclipse.

Is this a bug from Eclipse or from RFTools. I cannot work with Eclipse anymore.
