[Jewelcli-users] Fwd: ParameterizedTypeImp support for an @Option

[Eduard W. <edi...@gm...>]

Hi,

Appologies for the possible duplicate email to the mailing list.

I'm trying to use a generalized type as a return type for an option.

@Option(...)
SomeType<SomeOtherType> getSomeType();

This fails with java.lang.ClassCastException:
sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast
to java.lang.Class

Seems generalized types are supported for lists, but not for "non-list"
types.
Is there any way I could use a generalized type as per the setup I have
above?

Also, is the project still being maintained/developed, would you be
interested in a patch adding support for the above (in case its not there
yet)?

Thanks,
Eduard
