    I would suggest a new section "Java 8 Lambda Expressions" for the "Java API Programming
Guide" which explains how to use lambdas (with examples) and configure maven. I think it makes
sense to rename the whole "flink-java8-tests" subproject to "flink-java8" and put some example
in there.

> Lambdas currently work only for {{filter}} and {{reduce(a,b)}}, because Lambda type extraction
is not in place right now.
> We need to extend the type extraction for lambdas to support the other functions.
