That's why we have you on the project :).. I found the main problem of
this kind to occur in the PrintSelectionJava plugin with a return type
of Vector<Vector<SrcMLElement>> which I have now changed to use
Vector<Vector<? extends SrcMLElement>>. This needed a few more changes,
but works out great when adding List<Method> or similar objects.
Thanks for the pointer. We'll still have to make some more modifications
to the existing source (f.ex. changing those Vectors to Lists), but so
far the addition of generics seems to be rather unproblematic and the
new for loops alone justify the switch.
