Gaojie Liu created HTTPCLIENT-2222:
--------------------------------------
Summary: ProtocolNegotiationException and
ConnectionClosedException with httpclient5
Key: HTTPCLIENT-2222
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2222
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (async)
Affects Versions: 5.1.3, 5.1.2
Environment: GNU/Linux 5.4 with JDK11.
Reporter: Gaojie Liu
We are using httpclient5 to talk HTTP/2 to a Netty H2 server and we are using a
pretty standard way to construct a HttpClient5 client as follows:
{code:java}
final IOReactorConfig ioReactorConfig = IOReactorConfig.custom()
.setSoKeepAlive(true)
.setTcpNoDelay(true)
.setSoTimeout(Timeout.ofMilliseconds(requestTimeOutInMilliseconds))
.setIoThreadCount(ioThreadCount)
.build();
final TlsStrategy tlsStrategy = skipCipherCheck ?
VeniceClientTlsStrategyBuilder.create()
.setSslContext(sslContext)
.setTlsVersions(TLS.V_1_3, TLS.V_1_2)
.build()
: ClientTlsStrategyBuilder.create()
.setSslContext(sslContext)
.setTlsVersions(TLS.V_1_3, TLS.V_1_2)
.build();
final CloseableHttpAsyncClient client =
HttpAsyncClients.customHttp2().setTlsStrategy(tlsStrategy)
.setIOReactorConfig(ioReactorConfig)
.setDefaultRequestConfig(RequestConfig.custom()
.setResponseTimeout(Timeout.ofMilliseconds(requestTimeOutInMilliseconds))
.setConnectionRequestTimeout(Timeout.ofMilliseconds(requestTimeOutInMilliseconds))
.setConnectTimeout(Timeout.ofMilliseconds(connectTimeOutInMilliseconds))
.build())
.build();
client.start(); {code}
When we deployed this to prod, we discovered the following exceptions in the
first 30 mins and later, it seems become more stable:
{code:java}

Is it a known issue?
We tried the latest release of httpclient5: 5.2-beta1, the
ConnectionClosedException exception would happen much more frequent.
Let me know if you need more information.
