After upgrading of what to what?

Without reproducer I can hardly debug it. From looking into  stack trace, few options are rising:

Not found all resources, not declared main class,  ivalid jnlp, network outage, corrutped cache...

Still the same issues - Main class - entry point of your applet was not found.

And still the same, only with additional info that main lcass should be named ultracam.



The java.security.PrivilegedActionException:  seems to indicate that teh issue is casued by uidate 
from systemj dk 7 to system jdk8, but not for sure.


General hints:

  - try to run the applet in offline mode (-Xoffline)
  - try to run the applet without any security restrictions (-nosecurity)
  - try to force run over http instead of https
  - try to remove /.config/icedtea-web/.appletTrustSettings
  - via itweb-settings -> extended applets security : try to  set security level to Low
  - if above fails, try to clear cache and run it again (only the off-line  maybe skipped as all 
off-line resources were already deleted) (-Xclearcache)

You can try to run the applet (and so with above switches) as javaws -html -..switches.. 
http://your.applets/page.html

Or set the variables for plugin:
itweb-settings  -> jvmsettings -> jvm arguments for plugin



Also you may next time try the complete log from terminal when run with --verbose switch or from 
icedtea-web's console, which you can access from error dialogue. (but in this case I'm not sure if 
it will help much more)
