Generated results for Character Java type are invalid

[dhoffer]

We are finding that a Java Character field is mapped to OpenAPI via:

"type": "string",
"format": "byte",
"maxLength": 1.0,

We do not think 'byte' is the correct format nor is it documented in the 3.1.0 spec. Also length types should be integers not floating point. Also another reason byte does not make sense is a Character is one char or 2 bytes (or could be more under special cases) in Java.

We think the correct OpenAPI for this would be:

"maxLength": 1,
"minLength": 0,
"type": "string",

Thanks,

Maybe format: char [1] would be even better. This implies the length of 1.

"type": "string",
"format": "char"

Hi @MikeEdgar yes that does seem reasonable.
