Timo Walther commented on FLINK-1062:
-------------------------------------
I talked to Stephan about the problems we have with type erasure in non-Eclipse
compilers. He suggested the following subtasks:
- Configure JDT compiler in the examples project -> I will do this in another
PR
- Configure JDT compiler for our quickstart projects -> I will do this in
another PR
- Do Type Extraction and check if generics are lost, give a meaningful
exception -> Done in my latest commit
- Give the possibility to annotate the types (as String , e.g: "(Long,
Double)" for Tuple2...) -> Annotations for lambdas seem not to be possible yet
(see also
http://stackoverflow.com/questions/22375891/annotating-the-functional-interface-of-a-lambda-expression),
any ideas?

> Reporter: Stephan Ewen
> Assignee: Timo Walther
> Fix For: 0.7-incubating

> Lambdas currently work only for {{filter}} and {{reduce(a,b)}}, because
