Summary

0000017: Hessian readResolve writeReplace issues.

Description

RSN-7
Hessian has problems serializing objects that use readResolve and writeReplace methods.

- Will not call readReplace or writeResolve unless they are declared public. This is not a huge issue, but normally these methods can be given any modifier and it will work.
- When I change the methods to public and readReplace/writeResolve is used on an object I get the following error:

com.caucho.hessian.io.HessianProtocolException: testing_Test: unknown code:z

Attached is a very simple object that I tried to serialize using hessian that will demonstrate the issue.
