[mdr-users] Newbie: org.netbeans.mdr.util.DebugException

Dear All,

I keep getting the following doozy of an Exception, both in my NetBeans IDE
under normal operation (whenever it's trying to bring up the list of methods
when I press '.') and when I myself try to use a WhereUsedQuery in my
NetBeans custom module.

Could anybody please shed some light on what it means and what causes it? Is
it something that shouldn't have been left in the production code? I think
(though am not sure) it started happening since I added save support (ie.
Serialization) to my module?

Your help would be much appreciated,

Richard
