How do I exclude hosts from going through an HTTP proxy with S3AsyncClient.crtBuilder()?

[armlesshobo]

As far as I can tell, it seems that the http.nonProxyHosts system property isn't accounted for in S3CrtProxyConfiguration. Is there some way to work around this?

I create the async client with this code:

S3AsyncClient.crtBuilder()
      .httpConfiguration(
          S3CrtHttpConfiguration.builder()
              .proxyConfiguration(
                  S3CrtProxyConfiguration.builder()
                          .build())
              .build());

The below code resolves my proxy issue, but breaks multipart downloads, because MultipartS3AsyncClient overrides the getObject method which throws an UnsupportedOperationException. Unfortunately, I can't use S3AsyncClient.builder(), because I need multipart enabled for downloads.

        final SdkAsyncHttpClient asyncHttpClient = AwsCrtAsyncHttpClient.builder()
                .proxyConfiguration(
                        ProxyConfiguration.builder()
                                .build())
                .maxConcurrency(connectionCount)
                .build();

        final var clientBuilder = S3AsyncClient.builder()
                .httpClient(asyncHttpClient)
                .credentialsProvider(() -> AwsBasicCredentials.create(accessKey, secretKey))
                .region(Region.of(region))
                .multipartEnabled(true)
                .multipartConfiguration(MultipartConfiguration.builder()
                        .thresholdInBytes(MULTIPART_UPLOAD_THRESHOLD)
                        .build());
