Research direction

Start with the Java Native client and the useGzipFeature setting, using the reported deserialization runtime error as the first diagnostic. Trace how gzip responses are handled before deserialization and compare the native client's behavior with the supported client path. Done means gzip-enabled native Java responses deserialize successfully without runtime errors, with a regression test if the existing test structure identifies a suitable location.
