You can get (some of?) the effects of stateless mixins/traits using the 
proposed Default Methods [1] coming in with Project Lambda. Given the 
lack of any active projects to do anything more than this, this would 
seem to be the most you could expect to get in Java 8.

For Java 9+ ... work with an OpenJDK Committer to write up a JEP [2].
