Introduction to OpenJDK

OpenJDK is the Sun's GPL release of JDK. Due to legal concerns, not all of JDK has been released under GPL, therefore either Sun's Binary Plugs or Redhat's IcedTea must also be installed. Installation also requires a binary copy JDK 6.0, which can be found at http://java.sun.com/javase/downloads/index.jsp (seeJDK for installation instructions).
