Examples of java.lang.reflect.InvocationTargetException

java.lang.reflect.InvocationTargetException
InvocationTargetException is a checked exception that wraps an exception thrown by an invoked method or constructor.
As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "target exception" that is provided at construction time and accessed via the {@link #getTargetException()} method is now known as the cause,and may be accessed via the {@link Throwable#getCause()} method,as well as the aforementioned "legacy method." @see Method @see Constructor

      if (ret[0] instanceof Exception) {
        throw (Exception)ret[0];
      }
      else {
        throw new InvocationTargetException(ret[0]);
      }
    }
    return (T)retSuccess[0];
