Cybersource-rest-client-java failure under Java 17

We use the cybersource-rest-client-java library for making merchant payments. Our code runs successfully under Java 11.

Porting to Java 17, we see the following failure when making API calls -

com.google.gson.JsonIOException: Failed making field 'java.io.Reader#lock' accessible; either change its visibility or write a custom TypeAdapter for its declaring type at com.google.gson.internal.reflect.ReflectionHelper.makeAccessible(ReflectionHelper.java:23) at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.getBoundFields(ReflectiveTypeAdapterFactory.java:203) at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.create(ReflectiveTypeAdapterFactory.java:112) at com.google.gson.Gson.getAdapter(Gson.java:531) at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.createBoundField(ReflectiveTypeAdapterFactory.java:137) at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.getBoundFields(ReflectiveTypeAdapterFactory.java:211) at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.create(ReflectiveTypeAdapterFactory.java:112) at com.google.gson.Gson.getAdapter(Gson.java:531) at com.google.gson.Gson.toJson(Gson.java:778) at com.google.gson.Gson.toJson(Gson.java:756) at com.google.gson.Gson.toJson(Gson.java:711) at com.google.gson.Gson.toJson(Gson.java:691) at Invokers.JSON.serialize(JSON.java:83) at Invokers.ApiClient.execute(ApiClient.java:1204) at Api.PaymentsApi.createPaymentWithHttpInfo(PaymentsApi.java:161) at Api.PaymentsApi.createPayment(PaymentsApi.java:146)

This all seems to come from one single line of debug logging in the ApliClient. execute method -

logger.debug("Network Response :\n" + json.serialize(response.headers()));

The response object here is an OK HTTP object, with Java IO members that do not work for this reflective serialization under Java 17

I have built my own copy of the library with this one line removed, and the code works for me under Java 17,

Start at the debug logging line in ApiClient.execute that calls json.serialize(response.headers()), then trace the reported failure through Invokers.JSON.serialize. Reproduce an API call under Java 17 and verify that response logging no longer triggers the Gson reflective-access exception while the request still completes successfully.
