Eclipse stopped working with Ubuntu upgrade to 14.04

Two days ago I upgraded to the latest Ubuntu 14.04. Everything was working fine, until I tried to open Eclipse that I use for Java development. It shows the loading window but the program never loads. I started Eclipse from command line:

eclipse -consolelog

I receive the following output:

The past two days I was searching the internet and the farthest I could reach was; deleting the "workspace" folder makes Eclipse starts but without any projects, plugins or settings.

Any idea how to resolve this issue?

Thanks in advance.

Answer taken from comments

Eclipse was installed from repository, I resolved the problem by re-installing a newer version of Eclipse from their official website and reconfigured my workspace!
