Ah, the test I wrote checked only the case that MessagePackFactory has
ExtensionTypeCustomDeserializers...https://github.com/msgpack/msgpack-java/blob/develop/msgpack-jackson/src/test/java/org/msgpack/jackson/dataformat/MessagePackFactoryTest.java#L69-L79
This can be a workaround. But anyway I'll fix it soon.
Thanks.
