Description

In schema hierarchy with more, than two layers by Code Generation all classes in parent classes tree are merged within child class.

For example, if you try to generate a model classes from SchemaC, which allOfs SchemaB (with discrimanator), and SchemaB (with discrimanator) allofs SchemaA (with discrimanator), you will get Java class SchemaC, which contains all attributes of SchemaC, SchemaB and SchemaA instead of extending class SchemaB. SchemaC does not extend any class at all. Could you please solve this issue. Some example code is down there (without root yaml file)
