NoClassDefFoundError: sun/security/action/PutAllAction  - while loading applet 

While I was trying to load an applet using b23 PIT - I got this exception. 
First Applet didnt load - I refreshed couple of times and applet loaded but gave the following error  - Only with New Plugin 

I clicked ok and repeatedly pressed refresh and at last Applet loaded fine.  


Even I had problem opening javaws application for the first time - it game an Error - No running Java instances - 
But second time it worked fine. 

Attached the screeshot.
