Note however that using the dollar sign is faster, as Java.type first tries to resolve the class name as it is originally specified, and the internal JVM names for inner classes use the dollar sign. If you use the dot, Java.type will internally get a ClassNotFoundException and subsequently retry by changing the last dot to dollar sign. As a matter of fact, it'll keep replacing dots with dollar signs until it either successfully loads the class or runs out of all dots in the name. This way it can correctly resolve and load even multiply nested inner classes with the dot notation. Again, this will be slower than using the dollar signs in the name. An alternative way to access the inner class is as a property of the outer class:

+ * Utility class that determines if a method or constructor is caller sensitive. It actually encapsulates two different

+ * to {@code sun.reflect} package, and an unprivileged one that is used when Dynalink doesn't have access to that
+ * package. Note that even the unprivileged strategy is ordinarily robust, but it relies on the {@code toString} method
+ * of the annotation. If an attacker were to use a different annotation to spoof the string representation of the
+ * {@code CallerSensitive} annotation, they could designate their own methods as caller sensitive. This however does not
+ * escalate privileges, only causes Dynalink to never cache method handles for such methods, so all it would do would
+ * decrease the performance in linking such methods. In the opposite case when an attacker could trick Dynalink into not
+ * recognizing genuine {@code CallerSensitive} annotations, Dynalink would treat caller sensitive methods as ordinary
+ * methods, and would cache them bound to a zero-privilege delegate as the caller (just what Dynalink did before it
+ * could handle caller-sensitive methods). That would practically render caller-sensitive methods exposed through
+ * Dynalink unusable, but again, can not lead to any privilege escalations. Therefore, even the less robust unprivileged
+ * strategy is safe; the worst thing a successful attack against it can achieve is slight reduction in Dynalink-exposed

+     *
+     * Binds the source object's properties to the target object. Binding
+     * properties allows two-way read/write for the properties of the source object.
+     *
+     * Example:
+     * <pre>
+     * var obj = { x: 34, y: 100 };
+     * var foo = {}
+     *
+     * // bind properties of "obj" to "foo" object
+     * Object.bindProperties(foo, obj);
+     *
+     * // now, we can access/write on 'foo' properties
+     * print(foo.x); // prints obj.x which is 34
+     *
+     * // update obj.x via foo.x
+     * foo.x = "hello";
+     * print(obj.x); // prints "hello" now
+     *
+     * obj.x = 42;   // foo.x also becomes 42
+     * print(foo.x); // prints 42
+     * </pre>
+     * <p>
+     * The source object bound can be a ScriptObject or a ScriptOjectMirror.
+     * null or undefined source object results in TypeError being thrown.
+     * </p>
+     * Example:
+     * <pre>
+     * var obj = loadWithNewGlobal({
+     *    name: "test",
+     *    script: "obj = { x: 33, y: 'hello' }"
+     * });
+     *
+     * // bind 'obj's properties to global scope 'this'
+     * Object.bindProperties(this, obj);
+     * print(x);         // prints 33
+     * print(y);         // prints "hello"
+     * x = Math.PI;      // changes obj.x to Math.PI
+     * print(obj.x);     // prints Math.PI
+     * </pre>
+     *
+     * Limitations of property binding:
+     * <ul>
+     * <li> Only enumerable, immediate (not proto inherited) properties of the source object are bound.
+     * <li> If the target object already contains a property called "foo", the source's "foo" is skipped (not bound).
