I am not sure that advice will help: the spec only covers the effects of 
tagging a class as serializable with the interface Serializable, but it 
does not explain how that tagging is technically done.  And this seems 
to be the point the OP is struggling with.  To resolve that question 
reading the JVM Specification might help, for example the section about 
the class file format:
http://docs.oracle.com/javase/specs/jvms/se8/html/jvms-4.html

Kind regards
