PacketSerializer deserialization fails without CIMD packet checksums #1

Closed marko-asplund closed 12 years ago

marko-asplund commented 12 years ago

Checksums are an optional feature of the CIMD 2 protocol. PacketSerializer fails when configured to work without checksums:

new PacketSerializer("ser", false);

here's a stack trace:
