Hello Emilian,
thank you, I will repost it to apache incubator.

I have patched version of NetBeans 7.4 but all patches are ugly. It does
not run with clean NetBeans. I have also ported it to 8.2 without problems
but it remains the same ugly patches. I need to do it right and probably
push something upstream.

work before?
Some API will be nice. I had heavily modified version of GdbDebuggerImpl.

> This sounds like isRemote() to me, although communication is not via SSH.
Mainly yes, but it is not true in all cases. It is few years I have done
the patching of GdbDebuggerImpl and cnd.makeproject so it may be better in
recent versions. I must investigate it.

It was school project so the name was not important. Now, I can rename it,
because of this colision.
