[java] Installing Java on OS X 10.9 (Mavericks)

If you only want to install the latest official JRE from Oracle, you can get it there, install it, and export the new JAVA_HOME in the terminal.

That's the cleanest way I found to install the latest JRE.

You can add the export JAVA_HOME line in your .bashrc to have java permanently in your Terminal:

echo export JAVA_HOME=\"/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home\" >> ~/.bashrc
