NPE when adding components to module project using Maven

[Peter Nabbefeld <pe...@gmx.de>]

Hello,

there seems to be a problem with Mutexes in NB 11.1

I'm just editing some old "experimental" code (NB module plugin using
Maven, changed dependencies to RELEASE110).

When adding some component (Action or Window), I'm getting an NPE after
clicking on "Finish" button:

java.lang.NullPointerException

I'm not yet sure, if this is a bug - could probably somebody else try to
add some component (preferred those Action or Window components, as I've
used them for testing) to a mavenized module project?

Kind regards
Peter
