[jira] [Created] (HTTPASYNC-164) ParseException: Invalid protocol
version when using proxy settings
Carlos created HTTPASYNC-164:
--------------------------------
Summary: ParseException: Invalid protocol version when using proxy settings
Key: HTTPASYNC-164
URL: https://issues.apache.org/jira/browse/HTTPASYNC-164
Project: HttpComponents HttpAsyncClient
Issue Type: Bug
Reporter: Carlos
Hi,
We have upgraded our Apache HTTP Client library from version 4.1.4 to 5.0.3. We are using the async API. Overall, it's working very good. The reason for the upgrade is the need of using the new retry feature. However, we have an endpoint that requires accessing through a proxy. The problem with this one is that it's returning the following error:
{code:java}
org.apache.hc.core5.http.ParseException: Invalid protocol version; error at offset 0: <[0x2e][0x2f][0x30][0x31][0x32][0x33][0x34][0x35][0x36][0x37][0x38][0x39][0x3a][0x3b][0x3c][0x3d][0x3e]>

{code}
Same invocation with the previous library version was perfectly. We've tried a few options, but all of them result in the same exception being thrown:
{code:java}
// Option 1
return HttpAsyncClientBuilder.create().setProxy(HttpHost.create("http://127.0.0.1:8080")).build();
// Option 2
final ProxySelector proxySelector = ProxySelector.of(new InetSocketAddress("127.0.0.1", 8080));
final HttpRoutePlanner routePlanner = new SystemDefaultRoutePlanner(proxySelector);
return HttpAsyncClientBuilder.create().setRoutePlanner(routePlanner).build();
// Option 3
return HttpAsyncClients.customHttp2().setRoutePlanner(routePlanner).build();
// Option 4
return HttpAsyncClients.custom().setProxy(HttpHost.create("http://127.0.0.1:8080")).build();
// Option 5
return HttpAsyncClientBuilder.create().setProxy(HttpHost.create("http://127.0.0.1:8080")).build();
{code}
Is there a way to solve this issue? Any way to restore the previous version configuration?
Thank you!
