Problem H2ConnectionException: Frame size exceeds maximum using
httpclient5-5.0-beta1
Hi all
I need to create a https client able to connect to HTTP2 enabled web sites.
I tried to access a known HTTP2 web site (https://korben.info <https://korben.info/>) as a test using one of the HTTP2 example provided in https://hc.apache.org/httpcomponents-client-5.0.x/examples-async.html <https://hc.apache.org/httpcomponents-client-5.0.x/examples-async.html>
The example is working when negociating protocols because the website is also accessible using HTTP 1.1, but when I try to force the use of HTTP2 via the method setVersionPolicy (parameter HttpVersionPolicy.FORCE_HTTP_2) of the HttpAsyncClientBuilder class, I finally have the following problem :
Exception in thread "main" java.util.concurrent.ExecutionException: org.apache.hc.core5.http2.H2ConnectionException: Frame size exceeds maximum

Any idea about a solution ?

Some servers refuse to use HTTP/2 even when the client sends a
perfectly valid HTTP/2 request unless HTTP/2 has been negotiated
through ALPN handshake. Those servers send back a HTTP/1.1 response to
a HTTP/2 request often causing the client to choke on the response.
ALPN is supported by Oracle Java as of version 9 only.
With Java 9 AsyncClientTlsAlpn [1] example works for me. See the log
