Description of the PR

Must fix #2655 (closed)

I have changed the code in defaultCodgen. Maybe it's too low level and must be done in abstractJava?

Another solution is to create another fromProperty for fromParameter with more parameters and force complexType with the $ref. But I'm afraid of losing all language-specific overriding.
