-----------------------------------

             Summary: Bad Error Message when trying to use expression keys on 
non-POJO types
                 Key: FLINK-1182
                 URL: https://issues.apache.org/jira/browse/FLINK-1182
             Project: Flink
          Issue Type: Bug
          Components: Java API, Scala API
    Affects Versions: 0.7-incubating
            Reporter: Stephan Ewen


It says "type is not composite (but is) and goes on talking about POJO types." 
I think that should be fixed.

{code}
Type GenericType<flink.tutorial.pagerank.PageRank.Page> is not a composite 
type. Key expressions are only supported on POJO types and Tuples. A type is 
considered a POJO if all its fields are public, or have both getters and 
setters defined

org.apache.flink.api.java.operators.Keys$ExpressionKeys.<init>(Keys.java:249)
