[jetty-users] Problems on 100-continue + HTTPS

[John Jiang <john.sha.jiang@xxxxxxxxx>]

I'm using Jetty 9.3.8, and made it supporting h2 and h2c, like the below info on starting the server.
2016-09-06 13:23:52.505:INFO:oejs.ServerConnector:main: Started ServerConnector@1f021e6c{HTTP/1.1,[http/1.1, h2c, h2c-17, h2c-16, h2c-15, h2c-14]}{0.0.0.0:9020}
...
2016-09-06 13:23:52.721:INFO:oejs.ServerConnector:main: Started ServerConnector@6fe7aac8{SSL,[ssl, alpn, h2, h2-17, h2-16, h2-15, h2-14, http/1.1]}{0.0.0.0:9021}

I used curl to test the server, like the below command,
  curl -k --http2 -H "Expect: 100-continue" -d "body" https://localhost:9021/body
then it just printed the following error:
  curl: (92) HTTP/2 stream 1 was not closed cleanly: INTERNAL_ERROR (err 2)
If remove 100-continue header, like,
  curl -k --http2 -d "body" https://localhost:9021/body
Or over HTTP, like
  curl -k --http2 -H "Expect: 100-continue" -d "body" http://localhost:9020/body
the results looked fine.

Is it a Jetty bug on supporting 100-continue over TLS?
