Summary: 0003836: HessianDebugState ClassCastException
Description:
We're seeing two possibly related issues with the Hessian Debug facilities in
our production environment. The first is the exception pasted below. The
second is that hessian debug will run for a few hours after we restart the
web app, then just die. We are running 3.1.19. Any ideas?

java.lang.ClassCastException: java.util.Date cannot be cast to
java.lang.Integer
