javassist broken on Jake

[Claes Redestad]

Hi,

this appears to be due to the implementation of #NonHierarchicalLayers 
proposal which is now in jake: 
http://openjdk.java.net/projects/jigsaw/spec/issues/#NonHierarchicalLayers

In short Optional<Layer> Layer.parent() has been replaced by List<Layer> 
Layer.parents()
