public final class IndexedImmutableSet_CustomFieldSerializer
extends Object
Dummy serializer. Otherwise, GWT, in processing JdkBackedImmutableSet -- even though that class
has a custom field serializer -- would generate its own version of this class, implemented in
terms of calls to ImmutableSet_CustomFieldSerializer, which is itself a dummy that we've
provided. That produces GWT compilation errors, albeit ones that are non-fatal (even with -strict
on, oddly).
