Ubuntu – Eclipse doesn’t start on Ubuntu

I am facing one issue from many days. Sometime eclipse working fine but sometime eclipse doesn't start. May be some issue in workspace, when I change my workspace then it is working fine. But why it doesn't start on my old workspace.

I also try this Solution 1, but no any success.

When I start eclipse it looking like this

but after some time it will looking like this

I found error from /workspace/.metadata/.log file
