Class JavaVersionChecker

java.lang.Object
  JavaVersionChecker

public class JavaVersionChecker
extends Object

The purpose of this class is to provide a Java2 (1.2.x) compatible class that can simply check the JVM version and put up a dialog message if the version isn't sufficiently recent. This class should be compiled and jar'd with JDK 1.2.2 so that any JVM 1.2.2 and higher can execute it. This is so that the user sees a nice informative message telling them their JVM is old, instead of the dreaded : Cannot find main class. Program will exit.
