[jboss-dev] Do we need mod_cluster.sar in "default" JBoss AS config?

[Bill Burke]

So, you're saying that running Apache HTTPD in front JBoss helps your 
development productivity in some way?  I doubt it.

IMO, define some sort of user/customer feedback loop to discover what 
should be added to a 'dev' profile.  In the meantime, make our best 
guess.  Less == more, IMO.
