Why do you need 300 line method to add this ?
It's what other server adapters do too for enabling profile is it not ?
Maybe we got it in the wrong place since this actually sounds like
something that all server adapters should be able to benefit from as
long as they are launched
with pure java.
I have added a profile integration with JBT servers based on the
integration of WTP servers.
That feature has worked with TPTP.

Install a Profiler plugin, like YourKit
(http://www.yourkit.com/features/eclipse/) which supports
Eclipse notion of Profile runs.
Then you should be able to run a profiler against any java launch,
including our server adapter.
I have tried to start a server from the Servers view using the Profile
button.
It works for Tomcat, but doesn't work for JBoss AS.
I have tried Tomcat 7, AS 7.1.1, AS 7.2.0, EAP 6.1 and YourKit 12.
As I can see, YourKit integrates with WTP Tomcat and generic adapter. I
suppose we would have to add the integration with YourKit or use manual
settings.
When starting a server in the debug or run mode, it can be profiled from
YourKit UI.
