Can't type some chars in REPL using Neo2 layout in MacOS: ')' '\' '[' '?'

[ombako]

I'm using Counterclockwise IDE Version 0.35.0.STABLE001 under OS X 10.11.6 and I use the Neo2 keyboard layout (https://neo-layout.org/).

I can't type some characters in the editor windows nor in the REPL: ')', '\', '[', '?'
If I switch to the German layout, everything works fine. Only under the other layout I cannot input those characters.

In the standard Eclipse edition working in a java project I don't have this issue.
Under Linux using CCW with the same Neo2 Layout there are no issues either.
So it has to be the combination CCW+OSX+Neo2
