java - signed JNLP applet hanging on load -

i have applet worked fine month ago hangs @ startup. locks browser process must killed. single applet causing problems.

the console log shows jnlp file loading , reloading. not sure if problem. no exceptions thrown. never reach security check. near bottom this:

 basic: relaunch because: [currently running jre doesn't satisfy (version/args)] 

this bottom part of console log.
