Could not initialize class coldfusion.security.ESAPIUtils

Hello -

I'm receiving the following error:

"Error","ajp-bio-8014-exec-4","04/16/14","02:03:05","cfadmin","Could not initialize class coldfusion.security.ESAPIUtils The specific sequence of files included or processed is: C:\ColdFusion10\cfusion3\wwwroot\CFIDE\administrator\topnav.cfm, line: 248 "

from one of the Coldfusion Administrator consoles on a production server that also affects a site hosted on the same jvm.  I've researched this error and found data pertaining to CF8 and CF9, but not to CF10.  Is there a fix that is available I've overlooked?

The server build details are as follows:

Thank you.
