To summarize, these are the test failures/errors:

        • StringPlatformChars (error — native code not found)
        • NewUnsafeString (did not use provided string)
        • APIExtraction (class file for TestClass not found)
        • ClassDependenciesTest (assertion error — null pointer in loadClass)
        • IgnoreSymbolFile (package sun.reflect.annotation is not visible)
