thanks, but it does not help. I register my service internally using a
JavaInterfaceContract in the implementation provider and it is the only

either this code
SpliceService spliceService = scaDomain.getService(SpliceService.class,

nor the old version below without the /SpliceService work.
Any other ideas?
