My understanding is that JVM looking for specific signatures for the
Java class library marker interface just like it does for main method.
hence interfaces like Serializable, Clonable have a specific meaning
to the jvm.



so, its roughly like an IoC principle: "Instead of I define myself,
you define me".



Am I correct ?



Please read the "Java Object Serialization Specification".





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
