The basic idea is to have a pluggable bootstrap. The bootstrap.start() should run
under its own classloader as TCL not the classpath otherwise all sort of side effects
break (e.g. loading property editors, and other dynamic classloading, etc.).

In JBoss the bootstrap is two stage (actually it is multiple).

1) To load the bootstrap implementation itself (the mc + profile service)
2) To load the bootstrap xmls

As long as the called code doesn't have to worry about setting the TCL itself
(error prone and it is not likely to know what the correct CL is) 
I don't have a problem.
