[infinispan-issues] [Red Hat JIRA] (IPROTO-187) Add support for marshalling null elements in collections/arrays

Add support for marshalling null elements in collections/arrays --------------------------------------------------------------- Key: IPROTO-187 URL: https://issues.redhat.com/browse/IPROTO-187 Project: Infinispan ProtoStream Issue Type: Enhancement Affects Versions: 4.4.0.Alpha1 Reporter: Nistor Adrian Priority: Major So far, protostream has minimal support for nulls. A top level null object is marshalled as the empty (zero bytes) message.   For the sake of backward compatibility we'll keep this behavior for top level, but we need a different approach for elements of an array or collection. In this case we need to use a null token. A new field will be added in WappedMessage to represent the null.
