Nonnull ignored in mutation parameters in 0.9.8

[stoyandekov7]

In 0.9.8, it appears if you want to make a mutation argument mandatory, you have to use @GraphQLNotNull. Any other annotation (like javax.annotation.Nonnull) is ignored.

@GraphQLMutation
public User getUser(@Nonnull String username) { //this should make username non-nullable
}
