Java exception

[Phil Moses <pbmoses@xxxxxxxx>]

   Hello,
We have had the following exception error thrown more than once, I am
currently trying to figure out what is causing the exception. (although
the logs are not providing me with enough information.) The error at
this point seems to have spawned when using a Netscape navigator
browser.

las server = 6.3.0
Ferrett = 5.51
