Formatting switches with patterns

[io7m]

Hello!

I have the following method:

  @Override
  public <R extends SLCommandResponseType> R serverSend(
    final SLServerName serverName,
    final SLCommandType<R> command)
    throws SLException
  {
    final var server =
      this.findServer(serverName);

    final var r =
      this.send(server, server.commandURI(), command);

    return switch (r) {
      case final SLError e -> throw errorServer(e);

      case SLCommandType<?> _,
           SLLoginCommandType _,
           SLLoginInfo _,
           SLLoginResponseType _,
           SLTransaction _,
           SLTransactionResponse _ -> {
        throw errorUnexpectedResponse(r);
      }

      case final SLCommandResponseType res -> {
        final var expectedType = command.responseClass();
        if (Objects.equals(res.getClass(), expectedType)) {
          yield expectedType.cast(res);
        } else {
          throw errorUnexpectedResponse(res);
        }
      }
    };
  }

It seems that the current Eclipse formatter doesn't understand patterns in cases like that. It seems that no matter what formatter settings I try to use, the method ends up formatted looking like this:

  @Override
  public <R extends SLCommandResponseType> R serverSend(
    final SLServerName serverName,
    final SLCommandType<R> command)
    throws SLException
  {
    final var server =
      this.findServer(serverName);

    final var r =
      this.send(server, server.commandURI(), command);

    return switch (r) {
      case final SLError e -> throw errorServer(e);

      case
        SLCommandType<?> _,SLLoginCommandType _,SLLoginInfo _,SLLoginResponseType _,SLTransaction _,SLTransactionResponse _ -> {
        throw errorUnexpectedResponse(r);
      }

      case final SLCommandResponseType res -> {
        final var expectedType =
          command.responseClass();
        if (Objects.equals(res.getClass(), expectedType)) {
          yield expectedType.cast(res);
        } else {
          throw errorUnexpectedResponse(res);
        }
      }
    };
  }

It will even exceed the 80 column limit to format like this.

I can obviously use @formatter:off, but I don't really want to have to do this around pretty much every switch expression.

Is this a known issue?
