Try printing out the @ISA of Admin_server::Parser::Plugin::FeedHandler, it should have Moose::Object in it. Simplest way to do that is

print join ", " => @{ Admin_server::Parser::Plugin::FeedHandler->meta-
+>superclasses }

I am also a little puzzled as to why Admin_server::Parser:: and Admin_server::Parser::Plugin::Feedhandler:: have BUILD, BUILDARGS, DEMOLISH and DEMOLISHALL defined in their symbol tables, those are methods in Moose::Object.
