Early versions of JBoss Cache simply wrote cached data to the network by writing to an
ObjectOutputStream
during replication. Over various releases in the JBoss Cache 1.x.x series this approach was gradually
deprecated
in favour of a more mature marshalling framework. In the JBoss Cache 2.x.x series, this is the only officially
supported and recommended mechanism for writing objects to datastreams.
