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.
> Type Extraction for Lambdas

> Components: Java API
> Affects Versions: 0.7-incubating
> Reporter: Stephan Ewen
> Assignee: Timo Walther
> Fix For: 0.7-incubating

> 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.
