Summary

Remove the undocumented system property -Djdk.reflect.useOldSerializableConstructor=true and the old implementation of sun.reflect.ReflectionFactory::newConstructorForSerialization.

Problem

JDK-8315811 reimplements sun.reflect.ReflectionFactory::newConstructorForSerialization with method handles and adds an undocumented system property -Djdk.reflect.useOldSerializableConstructor=true to workaround any issue in JDK 22. This issue proposes to remove the system property and old implementation.

Solution

Remove the undocumented system property -Djdk.reflect.useOldSerializableConstructor=true as well as the old implementation of sun.reflect.ReflectionFactory::newConstructorForSerialization.

Specification

After this change, setting -Djdk.reflect.useOldSerializableConstructor=true system property has no effect. Note that this system property is undocumented and no documentation needs to be updated.
