code: @Override
      public void run() {
          try {
              handle();
          } catch (Exception e) {
              Throwables.throwIfUnchecked(e);
              throw new RuntimeException(e);
          }
      }
docs: Similar to {@link #handle()} but intended for execution on any thread.<p/>
  May throw a runtime exception in case something went wrong invoking the target saga message handler.
