I have added a profile integration with JBT servers based on the 
integration of WTP servers.
That feature has worked with TPTP.

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.
