the class ImmutableChecker method handleAnonymousClass.

// Anonymous classes
/**
 * Check anonymous implementations of {@code @Immutable} types.
 */

    if (superType == null) {
        return NO_MATCH;
    }
    // We don't need to check that the superclass has an immutable instantiation.
    // The anonymous instance can only be referred to using a superclass type, so
    // the type arguments will be validated at any type use site where we care about
    // the instance's immutability.
    // 
    // Also, we have no way to express something like:
    // 
    // public static <@Immutable T> ImmutableBox<T> create(T t) {
    // return new ImmutableBox<>(t);
    // }
    ImmutableSet<String> typarams = immutableTypeParametersInScope(sym, state, analysis);
