Commit Message

Refactor JavaSerializer, UnsafeSerializer, and BeanSerializer to eliminate code duplication (#57)

* Initial plan

* Refactor JavaSerializer and UnsafeSerializer to use FieldBasedSerializer base class

Co-authored-by: wuwen5 <5037807+wuwen5@users.noreply.github.com>

* Complete refactoring - consolidate writeReplace methods and fix module access

Co-authored-by: wuwen5 <5037807+wuwen5@users.noreply.github.com>

* Address code review feedback: move setAccessible to JavaSerializer only, remove writeObject10 from base classes

Co-authored-by: wuwen5 <5037807+wuwen5@users.noreply.github.com>

* Refactor JavaSerializer to reuse parent introspection and remove unused writeFieldValue method

Co-authored-by: wuwen5 <5037807+wuwen5@users.noreply.github.com>

* Remove unused writeObject10 methods and writeReplaceFactory field

Co-authored-by: wuwen5 <5037807+wuwen5@users.noreply.github.com>

* Rename writeReplace field to writeReplaceMethod to avoid confusion with superclass method
