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
