Re: [GridSim-users] DataGridResource - processing DataGridlets

As I get no feedback from this bug, and I didn't want to check the integrity of
GridSim after changing this, I've implemented another solution for the bug.
Basically, I added a new event CTLG_GET_REPLICA_FROM_RM with its corresponding
CTLG_REPLICA_DELIVERY_TO_RM that it is only processed from the Replica Manager
(so Replica Catalogue ignores that).

It would be nice to know if there is any official mechanism to report a bug and
its solution (or at least who I should discuss it with).

Thanks,

	Jonathan
