[jboss-dev] Small boottime improvement

[Brian Stansberry]

I can account for a couple differences between minimal and 
jbossweb-standalone:

1) conf/jboss-service.xml in minimal does not include this huge addition 
to the server classpath:

<classpath codebase="${jboss.common.lib.url}" archives="*"/>

Adding that to minimal increases it's startup time for me from ~ 6.4s to 
~ 6.8s.  BTW, Dimitris, I want a machine like his 2.6s one. ;-)

2) The ServiceBindingManager config in minimal is just an empty 
placeholder; in jbossweb-standalone it's the real thing. Putting that 
one in minimal increases its boot time to ~ 7.2s.
