Solution:1

  • Install more RAM ;)
  • Do you mean running in sense of processes?
  • Open a terminal and look for the java installations:
    ls /usr/lib/jvm/
  • Have you used the package manager? Then remove it with the software-center.
  • Look here if you installed from oracle: [


Solution:2

You can use update-alternatives

sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/java-6.45-oracle/bin/javac" 1  

and then follow it with a command

sudo update-alternatives --config javac
