It seems I've hit a bug in javac:
LambdaModelTest[46,61] reference to of is ambiguous:
<T> of(SerializableSupplier<T>, SerializableConsumer<T>)
<X,T> of(IModel<X>, SerializableFunction<X,T>)
This clearly is wrong:
IModel<String> personNameModel = LambdaModel.of(
() -> person.getName(),
(name) -> person.setName(name));
The first parameter could match both SerializableSupplier<T> and IModel<X>,
but the second parameter only matches SerializableConsumer<T>. Eclipse has no
problem with this and compiles the code just fine.
This now surfaces due to the change in the constructor. This testcase used to
call new LambdaModel(...), which had the same signature as the first 'of'. I
had to change it to use the overloaded factory method.
I see two possible solutions:
- Change the name of the factory methodes, so they are no longer overloaded
(suggestions for the names are welcome)
- Add a cast to the calling code to circumvent the bug.
IMHO both are ugly.
Best regards,
Emond
