Hi all,
I am trying to use Mapbinder to configure a plugin-like API. Long
story short, I need to inject a Map<Class, Class>, so I was thinking
about using Mapbinder, but AppEngine is complaining about the
mechanism used to inspect the generics info.
I have tried three alternatives and no one works:
MapBinder.newMapBinder(binder(), Class.class, Class.class,
JacksonMixins.class);
TypeLiteral<Class> typeLiteral = new TypeLiteral<Class>() {};
MapBinder.newMapBinder(binder(), typeLiteral, typeLiteral,
JacksonMixins.class);
TypeLiteral<Class<?>> typeLiteral = new TypeLiteral<Class<?>>()
{};
MapBinder.newMapBinder(binder(), typeLiteral, typeLiteral,
JacksonMixins.class);
JacksonMixins is a binding annotation. I have to double-check this,
but I think that it is not complaining about other Multibinders that
I'm using - just Mapbinder.
The stack trace follows. Any help would be much welcome.
