RFR: 8359809: AttributeList, RoleList and UnresolvedRoleList should never accept other types of Object [v2]

[Kevin Walls]

> The classes javax.management.AttributeList, and javax.management.relation.RoleList and UnresolvedRoleList, have a historical feature where they accept objects of the wrong type, and only check for wrong objects when the "asList()" method is called.
> 
> This feature should be removed, and these classes should never accept the wrong kind of Object.
