I have had working Java environment til Yesterday, I cleared my all files and folders in /tmp/ then restarted my computer after that I can not get any Java applications (Chrome, Firefox, Thunderbird, and etc) to work on my Ubuntu 14.04 computer.
I started Google Chrome and checked the System Monitor processes, process chrome status changed from uninterrupted to running and suddenly it gone away from the process list.
If anyone can suggest how debug this issue I would be grateful.
NOTE: I work on Oracle Java 1.8.0.25
/tmp
automatically, so next time, just reboot. In this case, if you would have a system backup, just restoring your system backup would take you 5 minutes to be back where you were before this heppened. Look at this Q&A how to perform one in the future. – Fabby Jan 23 '15 at 12:06
