Description
Given a class which has a type parameter, and is not used as super class.
public final class Wrapper<V> {
private final V value;
public Wrapper(V value) {
this.value = value;
}
// Getters, etc...
}When used in a constructor/setter for deserialization, with a type that requires the use of a converter, the converter is not called and the value is not converter, resulting in a ClassCastException later in the code.
For example, used in correlation with an Enum (which use a converter to be mapped to a String):
@Document
public class Foo {
private final Wrapper<FooEnum> myEnum;
@PersistenceConstructor
public Foo(Wrapper<FooEnum> myEnum) {
this.myEnum = myEnum;
}
// Getters, etc ...
public enum FooEnum { FOO, BAR }
}I have reproduced this behaviour with other classes which use a converter.
This issue looks like the #2226 one, but here we're in the case were the wrapper class is not extended with a given type.
