Unpack method doesn't work in JDK17 #600

0.9.0

This version support reading and writing Timestamp values. Packer and unpacker interfaces added pack/unpackTimestamp methods.

Timestamp value in MessagePack is an extension type value whose code is -1. You can read TimestampValue object with MessgageUnapcker.unpackValue method. If you are using low-level unpack methods (e.g., unpackInt, unpackExtension, etc.), you need to read unpackExtensionHeader first, and if extHeader.isTimestampType() is true, call unpackTimestamp(extHeader).

Timestamp values are represented with java.time.Instant objects. You can extract the unixtime value with Instant.getEpochSecond(), unixtime with milliseconds resolution with Instant.toEpochMilli(), and nano-resolution time with Instant.getNano().

As TimestampValue is just a sub class of ExtensionValue, no change requierd in your code that are traversing MessagePack data with MessageUnpacker.unpackValue method.

Added Timestamp support #565 and low-level APIs #580 for reading timestamp values.
