Unexpected Netty TLS 1.3 warnings #933

Closed andyrobinson closed 2 years ago

andyrobinson commented 2 years ago

Describe the bug When making an HTTP client request to an external service (Apple News), we see the following warning in the logs:

ReferenceCountedOpenSslContext BoringSSL doesn't allow to enable or disable TLSv1.3 ciphers explicitly. Provided TLSv1.3 ciphers: 'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384', default TLSv1.3 ciphers that will be used: 'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256'. To Reproduce Steps to reproduce the behavior: We are using the Finagle Http client (com.twitter.finagle.Http) to make the request. We are using Http.client.withTransport.tls to build the client and specifying the requestTimeout and noFailFast.

Expected behavior We would not expect to see warnings in the logs

Environment Finatra version 22.1.0 Finagle version 22.1.0
