[bv-dev] ExecutableDescriptor#getReturnValueDescriptor() and void methods

Hi all, Currently the method ExecutableDescriptor#getReturnValueDescriptor() returns null for methods which have no return value. Alternatively we could return a descriptor, which has no constraints, is not cascaded etc. and has an element class of void.class. This might allow for a more regular processing without null checks when working with a collection of executable descriptors. Any thoughts? Thanks, --Gunnar
