Applet does not run and crashes 7u55 plugin in chrome, Firefox and IE work fine

Question

My applet in the webpage does not open and the Java plugin becomes unresponsive and chrome freezes out. I am new to Java Web Services. Any help will be appreciated.

Java Plug-in 10.55.2.14
Using JRE version 1.7.0_55-b14 Java HotSpot(TM) Client VM

I'm getting the exact same NPE stack trace with JRE version 1.8.0_05-b13 Java HotSpot(TM) 64-Bit Server VM, running a Java Webstart application. — Dr.Haribo, Apr 25 '14 at 19:46

There is a multitude of known bugs regarding NullPointerException when calling EventQueue.invokeLater() after 7u25. Some of them are:

8017776, which was fixed in 8 and backported to 7u60 (b01).
8019274. Attempted fixes include this solution.

The fix for 8019274 might help you if the fix for 8017776 did not.

7u60 (nightly) still does not work. It seems your links points to other issues. – Gabriel May 16 '14 at 14:47
Looks like this exception had nothing to do with the crash .. Applet crash is still not known . Fixed it by replacing current "embed" tag with "applet" tag ! – aguli Jun 20 '14 at 20:01
