> As said in a comment of ticket HTTPCLIENT-2120 following a description of the error handling issue:
> When I unbiasedly tried to establish a HTTP/2 connection via HTTP-Proxy I noticed that in the logs there is a frame size error that is not obvious from the exception thrown by {{Future<SimpleHttpResponse>}}{{.get()}}:
> * In the logs I can see {{Code FRAME_SIZE_ERROR}} and {{Frame size exceeds maximum}} which might be caused by trying to consume the HTTP-1.1 proxy response as HTTP/2
> ** The associated Exception ({{H2ConnectionException: Frame size exceeds maximum}}) is omitted in {{org.apache.hc.core5.http2.impl.nio.AbstractH2StreamMultiplexer.onException(Exception)}} where {{((ExecutableCommand) command).failed(new ConnectionClosedException())}} is called
> The following snipped can be used to reproduce the issue ({{coconutpi:8080}} points to a basic squid 4.6 setup on a raspberry pi in my home network):
> {code:java}
> CloseableHttpAsyncClient client = HttpAsyncClients.custom().setVersionPolicy(HttpVersionPolicy.FORCE_HTTP_2)
> .setProxy(HttpHost.create("coconutpi:8080")).build();
> client.start();
> // throws org.apache.hc.core5.http.ConnectionClosedException: Connection is closed
> client.execute(SimpleHttpRequests.get("https://http2.pro/client"), null).get();
> {code}
