Error: "module java.base does not "opens java.lang" to unnamed module"

Java 11 または 17 で失敗を再現し、次に TokenRequestBasedAuthenticator.getToken から開始して、ResponseUtils.getValue と Gson のリフレクティブアクセスを通るスタックを追跡します。トレースから、失敗しているパスと、再現のエントリポイントである KeyProtectTest.basicTests が特定できます。影響を受ける Java バージョンで、JVM のワークアラウンドなしにトークン取得が動作すれば完了です。

Using the Key Protect Java SDK with Java 11 and Java 17, I am getting the error in the subject of the issue (stacktrace below).
While there are JVM workarounds, which I cannot rely on, ultimately it is up to the framework, in this case the Key Protect SDK, to update its code.
Could we get.a fix in the SDK for this?
