Make `BeanDeserializerModifier`/`BeanSerializerModifier` implement `java.io.Serializable`

[k163377]

Is your feature request related to a problem? Please describe.

The BeanDeserializerModifier does not currently implement Serializable.

jackson-databind/src/main/java/com/fasterxml/jackson/databind/deser/BeanDeserializerModifier.java

Line 48 in 5be890c

public abstract class BeanDeserializerModifier

On the other hand, this class is used as a field in SimpleModule which implements Serializable.
This means that if a simple implementation of BeanDeserializerModifier is used in a SimpleModule, the JDK serialization may cause unintended errors.

jackson-databind/src/main/java/com/fasterxml/jackson/databind/module/SimpleModule.java

Line 94 in 5be890c

protected BeanDeserializerModifier _deserializerModifier = null;

Describe the solution you'd like

Either have BeanDeserializerModifier implement Serializable or provide a base class like SimpleBeanDeserializerModifier that implements Serializable as well as other supporting classes.

Hmmh. Interesting. Yes, at least for Jackson 2.x this would make sense. Same wrt BeanSerializerModifier.

@cowtowncoder,

To ensure clarity, is the solution as straightforward as incorporating implements Serializable into the BeanSerializerModifier class? If that's the case, I could submit a PR.

@mukham12 I haven't had a look but I think that'd be it. So both BeanSerializerModifier and BeanDeserializerModifier. And against 2.17 branch (default).
