Generation hangs when schemas referencing each other

[nandi95]

When I'm defining my schemas and they're referencing each other the generation hangs. Consider the following example.

// UserSchema.php
return Schema::object('User')
            ->properties(
                Schema::array('vehicles')->items(VehicleSchema::ref())->description('The related vehicles')->default(null),
             )

// VehicleSchema.php
return Schema::object('Vehicle')
            ->properties(
                Schema::object('user')->additionalProperties(UserSchema::ref())->description('The user relation')->default(null),
             )

Both of these are implementing the Reusable interface.

Schema::object('user')->properties(UserSchema::ref())->nullable()->description('The vehicle owner'),
UserSchema::ref('user'),
Schema::object('user')->additionalProperties(UserSchema::ref())->nullable()->description('The vehicle owner'),

none of the baove solutions work either. Is this a bug @vyuldashev ?

Edit: self::ref() also does not work.
