After purging and reinstalling eclipse with dpkg (Ubuntu) there is an error throws there:

The first recommendation is to NOT install Eclipse from any Linux package manager or software repository. Instead, just get it from http://www.eclipse.org/downloads/. The builds that linux distro's install are often modified (mangled, some would say).
