        public static java.lang.Exception rethrowAsException​(java.lang.Throwable e)
                                              throws java.lang.Exception
        Rethrows the given Throwable, allowing the caller to declare that it throws Exception. This is useful when your callers have nothing reasonable they can do when a Throwable is thrown. This is declared to return Exception so it can be used in a throw clause: 
         try {
   doSomething();
 } catch (Throwable e} {
   throw Throwables.rethrowAsException(e);
 }
 doSomethingLater();
        Parameters:
        e - exception to rethrow
        Returns:
        does not return anything
        Throws:
        java.lang.Exception
