In order to support fields of the same name in subclasses we are now prefixing them with name of the class that defines them. To provide convenient way to access them from generated bytecode and also directly from JavaScript, there is a getter/setter function for each field. It starts with _ followed by the field name. If called with a parameter, it sets the field, with a parameter it just returns it.

29 * InvocationTargetException is a checked exception that wraps
30 * an exception thrown by an invoked method or constructor.
32 * <p>As of release 1.4, this exception has been retrofitted to conform to
33 * the general purpose exception-chaining mechanism. The "target exception"
34 * that is provided at construction time and accessed via the
35 * {@link #getTargetException()} method is now known as the <i>cause</i>,
36 * and may be accessed via the {@link Throwable#getCause()} method,
37 * as well as the aforementioned "legacy method."
