Description

jaxrs-resteasy-eap generates invalid Bean Validation annotations for properties of the following type:

type: integer
format: int64
maximum: 9999999999

which are represented as Longs in generated Java code.

The generated Bean Validation annotation is @Max(9999999999) and the project doesn't compile, because 9999999999 is greater than Integer.MAX_VALUE.
The generated annotation should be @Max(9999999999L).
