There is a common pattern with libraries which use anonymous inner classes to create an object like a Class object but with generic types attached to it, for use as keys with Lookup-like services:

bind(new TypeLiteral<List<MockUser>>() {}).toProvider(users);

This pattern is used by Guice's TypeLiteral and Jackson's TypeReference - and it is the way anything that needs this sort of thing will have to do it.

Reformat code in NetBeans always splits this idiom in a way which makes it much less readable:

            bind(new TypeLiteral<List<MockUser>>() {
            }).toProvider(users);

It would be better if there were a special case for anonymous inner classes with no members.
