Hi, I am trying (and very much failing) to set up a test for the http2 client proxy addition, the SSL-enabled path (SOLR-16859).
While trying to use JettySolrRunner's proxy (SocketProxy) I realized that it doesn't seem to actually work with SSL enabled. looking for other usecases in the Solr test pool I noticed all of the existing proxy tests have the `@SuppressSSL(bugUrl = " https://issues.apache.org/jira/browse/SOLR-5776";)` annotation. SOLR-5776 has been fixed for a good while now and there is some indication that the annotation should be removed, so I tried it on one of these other proxy tests (HttpPartitionOnCommitTest) and sure enough it failed with the same exception I was seeing. "No available authentication scheme" [0] I think the proxy impl is broken with SSL enabled, or somehow missing some important setting. Could someone with more knowledge in the area take a look? You can use my PR for verification, I have added a seed that enables SSL https://github.com/apache/solr/pull/1779/files#diff-2711752067ddc6eebaff3bb06836efdc0bbe07b9a7f780f35c2eb88b429c565cR70 the test passes on non-SSL settings. best, alex [0] 2> 2659 INFO (SocketProxy-Acceptor-64194) [] o.a.s.c.s.c.SocketProxy accepted Socket[addr=/127.0.0.1,port=64200,localport=64194], receiveBufferSize: 408300 2> 2662 INFO (SocketProxy-Acceptor-64194) [] o.a.s.c.s.c.SocketProxy proxy connection Socket[addr=/127.0.0.1,port=64195,localport=64201], receiveBufferSize=408300 2> 2689 ERROR (SocketProxy-Request-64200:64195) [] o.a.s.c.s.c.SocketProxy No available authentication scheme 2> => javax.net.ssl.SSLHandshakeException: No available authentication scheme 2> at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:131) 2> javax.net.ssl.SSLHandshakeException: No available authentication scheme 2> at sun.security.ssl.Alert.createSSLException(Alert.java:131) ~[?:?] 2> at sun.security.ssl.Alert.createSSLException(Alert.java:117) ~[?:?] 2> at sun.security.ssl.TransportContext.fatal(TransportContext.java:347) ~[?:?] 2> at sun.security.ssl.TransportContext.fatal(TransportContext.java:303) ~[?:?] 2> at sun.security.ssl.TransportContext.fatal(TransportContext.java:294) ~[?:?]
