What is jboss-serialization.jar, introduced in JBoss Cache 1.4.x and do I need this?
jboss-serialization.jar is the JBoss Serialization library, which is much more efficient in terms of speed and CPU usage as well as the generated byte stream size than standard Java serialization. This very significantly improves replication performance of custom objects placed in the cache. From 1.4.x, JBoss Cache relies on this library and it is needed to run JBoss Cache.
