Hi all,
I got this exception while shutting down the G-Reg server on the trunk. This
just happened once and I was unable to reproduce. It seems to be an issue in
the order of shutting down bundles. It seems that the BAM bundle is still
trying to access the registry when the registry service is down. Stopping
the BAM bundle when the registry service gets un-registered should solve
this problem, I believe.
