             Summary: TypeExtractor.analyzePojo has some problems around the default constructor detection
                 Key: FLINK-2437
                 URL: https://issues.apache.org/jira/browse/FLINK-2437
             Project: Flink
          Issue Type: Bug
          Components: Type Serialization System
            Reporter: Gabor Gevay
            Assignee: Gabor Gevay
            Priority: Minor


If a class does have a default constructor, but the user forgot to make it public, then TypeExtractor.analyzePojo still thinks everything is OK, so it creates a PojoTypeInfo. Then PojoSerializer.createInstance blows up.

Furthermore, a "return null" seems to be missing from the then case of the if after catching the NoSuchMethodException which would also cause a headache for PojoSerializer.

An additional minor issue is that the word "class" is printed twice in several places, because class.toString also prepends it to the class name.
