/**
* The {@link SerializableObjectInputStreamImpl} extends an ordinary
* {@link ObjectInputStream} to also resolve primitive types. In former JDKs
* (not tested with current ones), primitive types caused problems when
* deserializing. This class addresses and patches this issue.
*
* Interesting enough that there were already virtual class definitions for the
* primitive types ("boolean.class" - {@link Boolean#TYPE}, "byte.class" -
* {@link Byte#TYPE}, "char.clas" - {@link Character#TYPE}, "int.class" -
* {@link Integer#TYPE}, "double.class" - {@link Double#TYPE}, "long.class" -
* {@link Long#TYPE}, float.class" - {@link Float#TYPE}).
