Exception occurs when constraint set on overriden method

[msche]

javax.validation.ConstraintDeclarationException: Only the root method of an overridden method in an inheritance hierarchy may be annotated with parameter constraints.

So this will cause the exception above:

public class A {
    public void method(Object arg) {...}
}

public class B extends A {
    @Override
    public void method(@NotNull Object arg) {...}
}

Exception message is as follows:

HV000151: A method overriding another method must not alter the parameter constraint configuration, but method public void org.uniknow.agiledev.tutorial.dbc.OverrideClass.method(java.lang.Object) changes the configuration of public void org.uniknow.agiledev.tutorial.dbc.BaseClass.method(java.lang.Object).

The exception is raised if you add parameter constraints to a method which overrides or implements a super-type method. This behavior is mandated by the Bean Validation spec (see http://beanvalidation.org/1.1/spec/#constraintdeclarationvalidationprocess-methodlevelconstraints-inheritance) in order to obey to the Liskov substitution principle:

Quote:
In sub types (be it sub classes/interfaces or interface implementations), no parameter constraints may be declared on overridden or implemented methods, nor may parameters be marked for cascaded validation. This would pose a strengthening of preconditions to be fulfilled by the caller.

Since the exception complies to the specs we won't fix this issue.
