Minor Description
Following the documentation here:
https://solr.apache.org/guide/solr/latest/deployment-guide/solrj.html
This code leads to an NPE:
Http2SolrClient mavenCentralRepo = new Http2SolrClient.Builder("https://search.maven.org/solrsearch").build();
final SolrQuery query = new SolrQuery("fc:" + className);
query.setRows(20);
QueryResponse response = mavenCentralRepo.query(query);
NPE:
java.lang.NullPointerException: Missing SslContextFactory at java.base/java.util.Objects.requireNonNull(Objects.java:246) at org.eclipse.jetty.io.ssl.SslClientConnectionFactory.<init>(SslClientConnectionFactory.java:57) at org.eclipse.jetty.client.HttpClient.newSslClientConnectionFactory(HttpClient.java:1208) at org.eclipse.jetty.client.HttpClient.newSslClientConnectionFactory(HttpClient.java:1214) at org.eclipse.jetty.client.HttpDestination.newSslClientConnectionFactory(HttpDestination.java:148) at org.eclipse.jetty.client.HttpDestination.newSslClientConnectionFactory(HttpDestination.java:154) at org.eclipse.jetty.client.HttpDestination.<init>(HttpDestination.java:94) at org.eclipse.jetty.client.MultiplexHttpDestination.<init>(MultiplexHttpDestination.java:25) at org.eclipse.jetty.http2.client.http.HttpDestinationOverHTTP2.<init>(HttpDestinationOverHTTP2.java:32) at org.eclipse.jetty.http2.client.http.HttpClientTransportOverHTTP2.newHttpDestination(HttpClientTransportOverHTTP2.java:128) at org.eclipse.jetty.client.HttpClient.lambda$resolveDestination$0(HttpClient.java:575) at java.base/java.util.concurrent.ConcurrentHashMap.computeIfAbsent(ConcurrentHashMap.java:1705) at org.eclipse.jetty.client.HttpClient.resolveDestination(HttpClient.java:573) at org.eclipse.jetty.client.HttpClient.resolveDestination(HttpClient.java:551) at org.eclipse.jetty.client.HttpClient.send(HttpClient.java:599) at org.eclipse.jetty.client.HttpRequest.sendAsync(HttpRequest.java:778) at org.eclipse.jetty.client.HttpRequest.send(HttpRequest.java:765) at org.apache.solr.client.solrj.impl.Http2SolrClient.request(Http2SolrClient.java:448) at org.apache.solr.client.solrj.SolrRequest.process(SolrRequest.java:217) at org.apache.solr.client.solrj.SolrClient.query(SolrClient.java:927) at org.apache.solr.client.solrj.SolrClient.query(SolrClient.java:940)
I think there is a bug in Http2SolrClient somewhere. Such URLs should be supported out of the box on a Java 11 JDK without requiring users to provide system properties or other custom initialization. Otherwise it should be documented but I couldn't find anything related to TLS/SSL configuration in the doc mentioned above.
