Just to make sure we are on the same page.

cdt.debug.core and cdt.debug.ui are debugger independent
meaning that they rely only on the functionnality provided
by the CDI.

CDI is a pure interface that a debugger engine must
implement.

You do not necessarly need an UI part unless you
want to provide some tweaks etc ..

So keeping the ascii art above in mind, not sure why you
would need SWT Messagbox, JFace etc ... since the policy
making is done by the higher levels cdt.core and cdt.ui.
