libjboss-serialization-java 1.0.3.GA+dak1-3 (i386 binary) in ubuntu precise

 JBossSerialization is a new approach to java-serialization. The main
 feature in JBossSerialization besides performance, is Smart Cloning.
 .
 Smart cloning is the capability of the reuse of final fields among
 different class loaders doing exactly what serialization does,
 without the need of convert every field into a byteArray. This
 approach is at least 10 times faster than using serialization over a
 byte array.
