Found one unresolved task: DeduplicationVisitor "swap inner classes for lambdas when we are on java 8"

We found this task where the condition satisfied but action was not taken:

cayenne-dbsync/src/main/java/org/apache/cayenne/dbsync/naming/DeduplicationVisitor.java:43

// TODO: swap inner classes for lambdas when we are on java 8

• The trigger: "when we are on java 8" happened around commit <b332610abdc3e4f0ec7743982c6f3c84b3436dde> (Aug 18 2017).

• But the action: "swap inner classes for lambdas" never happened since then.

• What need to be done: replace the inner classes, mostly

  new Predicate(){...}

  with lambdas introduced in Java 8.
