Eclipse keeps Crashing randomly in Ubuntu 14.10

I am running Eclipse Luna on my Ubuntu 14.10. But, It is getting crashed again and again. Sometimes just after startup and sometimes while working on it. This behaviour is very random.

I looked for some workarounds on the internet. one of which was adding following line in the eclipse.ini file

-Dorg.eclipse.swt.browser.DefaultType=mozilla

but, it is still crashing.

I ran eclipse from command line and this is what happened when it starts and then it crashes and print last line in the following output

org.eclipse.m2e.logback.configuration: The org.eclipse.m2e.logback.configuration bundle was activated before the state location was initialized. Will retry after the state location is initialized.
