Whenever you install a new version of Java, the old one is not deleted. Sun does this just in case some old applications won’t work with the latest Java version. These different previous versions occupy quite some amount of space and sometimes even cause issues with some applications.
JavaRa is a free tool that will permanently remove all old, vulnerable and redundant versions of Java Runtime Environment from your system. JavaRa checks if your computer has the latest version of Java Runtime Environment (JRE), otherwise it’ll start the Java Update Program to update the current version of JRE. JavaRa then allows you to remove all possible older versions of this program. This will ensure that the security of your computer is enhanced and extra space on your hard disk is created.
