OkHttp3 - IOException: unexpected end of stream on okhttp3.Address@9d7c59b5 #2738
Description
The error occurs when OkHttp try to reuse a connection that is in FIN_WAIT2 state in server, because the server keep_alive timeout is lesser than the client timeout.
StackTrace:

Steps to reproduce:
-Configure a Tomcat(7 or 8) Server with a keep_alive timeout of 60 seconds (default);
-Create a OkHttpClient with retryOnConnectionFailure(false) and the default ConnectionPool (5 min timeout);
-Do a GET request with client.newCall(request).execute();
-Wait more than 60 seconds (or monitor the connection state, until FIN_WAIT2 state);
-Do a GET request with client.newCall(request).execute(), using the same client;
Sample code:
OkHttpClient client = new OkHttpClient.Builder()
.retryOnConnectionFailure(false)
.build();
for (int i=0; i != 10; i++) {
Response response = client.newCall(new Request.Builder()
.url("http://localhost:8080/")
.get()
.build()).execute();
try {
System.out.println(response.body().string());
} finally {
response.close();
}
Thread.sleep(61000);
}
