TypeVariableImpl cannot be cast to java.lang.reflect.ParameterizedType (Related to Issue # 146} #174

Unable to generate the jsondoc json with latest released version 1.2.10. It happens when an object field is of collection type with generics. This seems to be related to Issue #146 but it falls on different code path.

public class ClassA<T> {
public List<T> objects;

Stack Trace:

Caused by: java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.TypeVariableImpl cannot be cast to java.lang.reflect.ParameterizedType
