Trying to install the TCF C/C++ Remote (over TCF/TE) Run/Debug Launcher is not compatible with CDT 9.0 Neon. I suspect the reason is that CDT decided to get rid of its GDB CDI interface (org.eclipse.cdt.debug.mi.core) but the TCF Launcher currently depends on it.

As part of the Neon Release train, we need to find a solution -- either 
a) stop contributing the TCF C/C++ Remote (over TCF/TE) Run/Debug Launcher, 
b) find a way that allows us to be compatible, or
c) discuss with the CDT not removing the stuff that we need.
Marked as a Blocker since this blocks our contribution to Neon M6. For now, I
am removing the C/C++ Remote Launcher contribution from our Neon contribution.

Steps to reproduce:

1. Download Eclipse SDK m6 Candidate org.eclipse.cdt.debug.mi.core :
   http://download.eclipse.org/eclipse/downloads/drops4/I20160308-0800/

2. Help > Install New Software from CDT master:
   https://hudson.eclipse.org/cdt/job/cdt-master/lastSuccessfulBuild/artifact/releng/org.eclipse.cdt.repo/target/repository/

3. Restart, Help > Install New Software from TCF 1.4 Neon M6 candidate:
   http://download.eclipse.org/tools/tcf/builds/1.4/milestones/20160312

The following error is shown when choosing C/C++ Remote Launcher:
