1) The fact that we are already having almost more than 200 message ids 
for EJB subsystem alone makes it look like a bit too much IMO. Looking 
at many of those messages, they are sometimes related to invalid 
arguments being passed to methods and we throwing 
IllegalArgumentException with a specific message id. Unfortunately, this 
appears to be repeated many times with different ids with a different 
message instead of just having a common id/message (perhaps across 
subsystems).
