Enhance java.time.Instant default value support ----------------------------------------------- Key: IPROTO-182 URL: https://issues.redhat.com/browse/IPROTO-182 Project: Infinispan ProtoStream Issue Type: Enhancement Reporter: Dan Berindei Assignee: Nistor Adrian Priority: Minor Fix For: 4.4.0.Final Because of IPROTO-114, I had to set a default value for {{java.time.Instant}} fields. The {{defaultValue}} javadoc says {{The value is given in the form of a string that must obey correct syntax (as defined by Protobuf spec.)}}, but the protobuf documentation isn't very clear on what the default value for a {{Timestamp}} field should look like, and {{java.time.Instant}} isn't exactly a {{Timestamp}} anyway. The correct default value format is a positive number, representing milliseconds since the UNIX epoch, but this format is not documented. But negative values should also be supported, because {{java.time.Instant}} can represent timestamps before the UNIX epoch. It would be even better to support the RFC 3339 format ({{"1972-01-01T10:00:20.021Z"}}) that protobuf uses when mapping a {{Timestamp}} to JSON.
