Summary: 0006392: Hessian can not support a class with a filed which is LocalDate when serializing
Description: We get an "StackOverflow Exception" while trying to serialize a class with a field which is LocalDate.

We create a small testcase to reproduce the bug. The testcase uses JavaSerializer and Hessian2Output to serialize a class A, which has a field called a_filed.

We finally find that JavaSerializer would use java.time.LocalDate#writeReplace to serialize LocalDate,which returns an object of java.time.Ser.The class of java.time.Ser has a field ,which is the object of LocalDate that class A has(a_filed).
So when JavaSerializer serialzes class A, it would use writeObject and cause an endless loop between serialzing a_filed and the object of java.time.Ser that java.time.LocalDate#writeReplace returns.
Steps To Reproduce:
Additional Information: The Exception stack is below:
