Replacing OpenJDK with JRE 6 in Arch Linux
In Arch Linux Wiki page, it mentioned that OpenJDK is nearly perfect which we need not to install Oracle proprietary Java. But sadly to know, there are some Java applet which needs Java Runtime Environment version 6 instead of 7. That means, neither OpenJDK nor Oracle proprietary Java 7 works.
