----------------------------------
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.
