/**
* This method is used to filter classes that are added to the {@link DeployedUnit}. When this
* method is used, only classes that are meant to be used with serialization are added to the
* deployment. This feature can be used to, for example, make sure that
* non-serialization-compatible classes (such as interfaces), do not complicate the use of a
* deployment with the remote services (REST/JMS/WS). Note to other developers, it's possible that
* classpath problems may arise, because of either classloader or lazy class resolution problems:
* I simply don't know enough about the inner workings of the JAXB implementations (plural!) to
* figure this out.
*
* @param deployedUnit The {@link DeployedUnit} to which the classes are added. The {@link
* DeployedUnit} to which the classes are added. The {@link DeployedUnit} to which the classes
* are added.
* @param classToAdd The class to add to the {@link DeployedUnit}.
