I downloaded httpcomponents-client-5.0-alpha2 which supports http2. I copied the example from https://hc.apache.org/httpcomponents-client-5.0.x/httpclient5/examples/org/apache/hc/client5/http/examples/AsyncClientHttp2ServerPush.java to see how does I should use it. But example itself fails with "Frame size exceeds maximum" in default size and "org.apache.hc.core5.http2.H2CorruptFrameException: Corrupt or incomplete HTTP2 frame" when I increase the frame to max.
I understand that this is not GA version. Would it helpful if someone can point me to right direction
"Frame size exceeds maximum"
this error may be due to you are accessing a site with HTTP1.1 protocol, try accessing a h2 protocol site.
