    I don't see a way to let ThreadGroupPredicate and ThreadPredicate inherit 
from java.util.function.Predicate. See my comment in 
[LANG-1417](https://issues.apache.org/jira/browse/LANG-1417). @salyh as author 
of the initial implementation, can you have a look please? Am I missing 
something?

> Since we upgraded the Java language requirement to Java 8, we can deprecate 
> our custom ThreadPredicate and ThreadGroupPredicate implementations.
> It looks like our initial plan to let ThreadPredicate and 
> ThreadGroupPredicate extend java.util.function.Predicate is not possible. 
> This is because auf AlwaysTruePredicate and NamePredicate extending both 
> interfaces. This leads to the situation that these classes would inherit from 
> both Predicate<Thread> and Predicate<ThreadGroup>, which is not possible.
