I am experiencing a strange behavior on Mac OS X with Java Applets deployed though the JNLP mechanism (i.e., exploiting the next-generation Java Plug-in).
For testing purposes, I have developed a VERY SIMPLE applet, just setting a BorderLayout on JApplet's contentPane, then adding sample JButtons on sides, and a sample JLabel in the center. Here is the code:
While this simple Applet works fine on Windows clients running a recent JRE, it displays NOTHING on recent Mac OS X clients (tested on both Mac OS X 10.7 and 10.8).
You can test this Applet yourself at:
Can some Mac users check if they obtain a blank screen on their Mac OS X clients as well?
Can someone guess why I am obtaining this behavior? A bug of Apple's implementation? If yes, it would be a really SERIOUS bug...
It is important to notice that this same applet displays fine on Mac if using the "old fashioned" <applet> tag (i.e., no JNLP).
Any feedback or hint would be greatly appreciated.
Thanks and best regards,
