when we launch a dragged out applets offline via desktop shortcut, applet cannot start and throw exception:

exception: null.
java.io.FileNotFoundException: JNLP not available: https://jdk6.dev.java.net/plugin2/DragExample.jnlp
at sun.plugin2.applet.JNLP2Manager.loadJarFiles(Unknown Source)

Exception: java.io.FileNotFoundException: JNLP not available: https://jdk6.dev.java.net/plugin2/DragExample.jnlp

this is similar to 6744967: Cannot launch cached Java Web Start applications while system is offline, but this time it's dragged applets.
