code: public static RuntimeException propagate(final Exception exception) {
          if (RuntimeException.class.isAssignableFrom(exception.getClass())) {
              return (RuntimeException) exception;
          }
  
          return new RuntimeException("Repropagated " + exception.getMessage(), exception);  //NOPMD
      }
docs: Propagate a Throwable as a RuntimeException. The Runtime exception bases it's message not the message of the Throwable,
  and the Throwable is set as it's cause. This can be used to deal with exceptions in lambdas etc.
  
  @param exception the Exception to repropagate.
  @return a RuntimeException
