MissingKotlinParameterException contains non-serializable KParameterImpl, breaking Throwable contract

[ghost]

Describe the bug

This bug is an offspring of spring-projects/spring-kafka#2306

As described there spring-kafka tries to serialize exceptions, which fails with

java.lang.RuntimeException: Could not deserialize type java.io.NotSerializableException with message kotlin.reflect.jvm.internal.KParameterImpl failure: kotlin.reflect.jvm.internal.KParameterImpl

To Reproduce

• Create an instance of com.fasterxml.jackson.module.kotlin.MissingKotlinParameterException
• Create an ObjectOutputStream and try to write the exception object into the stream

Expected behavior

As MissingKotlinParameterException implements Serializable it should be serializable without any execptions.

Three options:
a) make KParameter property transient
b) implement special handling of non-serializable properties by implemeting writeObject/readObject
c) Request the kotlin people to implement KParameter classes as serializable

Versions
Kotlin: 1.7.0
Jackson-module-kotlin: 2.13.3
Jackson-databind: 2.13.3

We are considering deprecating MissingKotlinParameterException in 2.16.
See #617 for details.

Aside from deprecation, if reference is directly from MKPR, perhaps that reference could be changed to transient to avoid the issue?

@cowtowncoder
It looks a good idea.
PR created.

@jeromewaibel
The fix we are trying to do will not allow us to read the parameter property when deserialized.

Would this be a problem in your use case?
I am not aware of the details of the original problem and would appreciate your confirmation.

@k163377 This should be fine for me.

#654 has been merged.
This issue is closed as resolved.
