If you create a jar file WITHOUT a “Main-Class” manifest field, and you try to run it by java –jar xxx.jar using Java 7 b147, you get this:
Exception in thread "main" java.lang.NullPointerException
at sun.launcher.LauncherHelper.getMainClassFromJar(LauncherHelper.java:399)
at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:463)
However if you do the same thing in Java 6, you get this:
Failed to load Main-Class manifest attribute from
stringbenchmarkmissingmainclass.jar
Exception in thread "main" java.lang.NullPointerException
at sun.launcher.LauncherHelper.getMainClassFromJar(LauncherHelper.java:399)
