        The spec for the methods
        http://docs.oracle.com/javase/8/docs/api/javax/script/ScriptEngine.html#put-java.lang.String-java.lang.Object-
        http://docs.oracle.com/javase/8/docs/api/javax/script/ScriptEngine.html#get-java.lang.String-

        says:
        "Throws:
        NullPointerException - if key is null.
        IllegalArgumentException - if key is empty."

        However the following code executed on Oracle's JDK.

                new ScriptEngineManager().getEngineFactories()
                        .stream()
                        .map(ScriptEngineFactory::getScriptEngine)
                        .forEach(e -> {
                            e.get("");
                            e.get(null);
                            e.put("", "a");
                            e.put(null, "a");
                        });

        results in no exceptions thrown which doesn't conform to the current spec and the corresponding JCK9(b05) tests will fail on JDK9:

        api/javax_script/ScriptEngineFactory/index.html#GetParameter[get_keyIsNull_NPE]
