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

Reproduce the failure on Java 11 or 17, then start at TokenRequestBasedAuthenticator.getToken and follow the stack through ResponseUtils.getValue and Gson's reflective access. The trace identifies the failing path and KeyProtectTest.basicTests as the reproducing entry point. Done means token fetching works without a JVM workaround on the affected Java versions.

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?
