"trivial", but I am going to fix:
* expected values in assertions should be put at the beginning;
* string comparison for classes is not really canonical. I'm going to
change it to Class.isInstance(Serializer)<http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Class.html#isInstance(java.lang.Object)>

Class.forName is evil for OSGi mates and would complain about it, I'm
going to add a new method
+--------+
public static Serializer createNewSerializer( String
serializerClassName, ClassLoader loader )
+--------+
and the default one will use the SerializerFactory.class.getClassLoader().

this is exactly the <S extends Serializer> S createNewSerializer(
Class<S> serializer ) method invocation, no needs to repeat the same
code.
