There isn't much to go on.  The error was generated on the server, the GUI is just reporting the failure.

The attached server log doesn't show much, I'm not sure if there was more context before or after the exception.  But it looks like some sort of network glitch or something.  We need to figure out if this is related to this one type of call or just endemic to the environment.

Hi Jay,

Same exception has been thrown on click of EAP_Server on UI. There was no other exception visible in logs. Will update the BZ with comment in case of reproduction with more "informative" log.
