Invoking InMoov2 services casts many java NullPointerExceptions

[Gleis1234]

I installed myrobotlab 1.1.701 and loaded the InMoov2 services over the intro icon. Opening the servo control section works fine, I can attach my servos and control them. But when I try to start InMoov2 services with the GO icon and load a configuration e.g. InMoov2_RightSide there is a lot of java NullPointerExceptions. No further action is possible.
The myrobotlab.log contains no actual data. Once I redirected the console output to a file. This I may reproduce if this would help.
