Gson Reflection in Java 17 Compatibility

[ranicza]

Hi guys, I encountered a compatibility issue when recently migrating to Java 17. There is an exception related to the use of the Gson library when it tries to parse exception

com.google.gson.JsonIOException: Failed making field 'java.lang.Throwable#detailMessage' 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) ~[gson-2.9.1.jar:na] at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.getBoundFields(ReflectiveTypeAdapterFactory.java:203) ~[gson-2.9.1.jar:na] at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.create(ReflectiveTypeAdapterFactory.java:112) ~[gson-2.9.1.jar:na] at com.google.gson.Gson.getAdapter(Gson.java:531) ~[gson-2.9.1.jar:na] at com.google.gson.Gson.fromJson(Gson.java:1057) ~[gson-2.9.1.jar:na] at com.google.gson.Gson.fromJson(Gson.java:1129) ~[gson-2.9.1.jar:na] at com.google.gson.Gson.fromJson(Gson.java:1101) ~[gson-2.9.1.jar:na] at com.kaltura.client.utils.GsonParser.parseException(GsonParser.java:283) ~[kalturaApiClient-19.3.0.jar:na]

As java 17's strengthened encapsulation model that restricts reflective access to internal APIs, impacting Gson's ability to serialize and deserialize exception details.
