Thanks for the reminder,
I think, you can pass the mentioned “-Dsolr.http1=true” parameter in the startup script. But this does not disable the HTTP/2 listener, it just makes SolrJ no longer use the Http2SolrClient and fall back to the old one. But that only affects the “new” solr servers as a “client” to old servers during rolling upgrade. I did a quick check, if the parameter makes its way to solr: yes, after starting solr with “-Dsolr.http1=true”: C:\..\solr-8.0.0\bin>solr start -e techproducts -Dsolr.http1=true … it showed the parameter in admin UI under system properties. But I did not test a full cluster in the short time. The HTTP/2 endpoint of the started server was still available, but outgoing solr requests should only go with HTTP1 then. I am sure somebody tested this in Linux, Windows is same as the system property reached the JVM, so startup scripts handle it right.

IMHO, we should respin as non-working startup script on Windows for users of secured Solr servers is a blocker.

I have not tested this but it looks like on Windows the if statement is missing. If we cannot fix this soon we may release a Bugfix Version later, but this would prevent Windows users from upgrading. So I switch to +/-0 to release. What do others think? I will try to fix startup script later, maybe it's easy.

First automated smoke testing with Policeman Jenkins resulted in a +1 from Policeman Jenkins: <https://jenkins.thetaphi.de/job/Lucene-Solr-Release-Tester/15/console> https://jenkins.thetaphi.de/job/Lucene-Solr-Release-Tester/15/console SUCCESS! [2:42:28.295475] The testing was done with Java 8 and Java 9 (this is why it took longer). I also checked Changes.txt, looks fine (there is only a few typos in the changes about the switch of Solr to HTTP/2, but that’s not horrible, but we should improve it, as its one significant change): latter -> later I also checked the ZIP files of Lucene and Solr. Lucene looks as usual, MIGRATE.txt is also fine – thanks for adding recent information! JAR files also look fine, compiled with correct version of Java and patches multi-release class files are there. Apache Solr was unzipped and quickly tested on Windows: Startup with Java 8 and Java 11 worked without any problems from a directory with whitespace in path. I was able to do a HTTP/2 request with CURL (non-TLS) on both O/S: Uwe Schindler@VEGA:~ > curl -I --http2 localhost:8983/solr/ HTTP/1.1 101 Switching Protocols HTTP/2 200 x-frame-options: DENY content-type: text/html;charset=utf-8 content-length: 14662 So, it worked. In the webbrowser it did not use HTTP/2, as browsers require SSL for that (by default). Next I enabled TLS support by creating a keystore. Unfortunately Solr did not start with Java 8. According to the documentation it should still start, but disable HTTP/2 by default. But it complained about no ALPN processors: Waiting up to 30 to see Solr running on port 8983 java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.eclipse.jetty.start.Main.invokeMain(Main.java:220) at org.eclipse.jetty.start.Main.start(Main.java:490) at org.eclipse.jetty.start.Main.main(Main.java:77) Caused by: java.security.PrivilegedActionException: java.lang.reflect.InvocationTargetException at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.jetty.xml.XmlConfiguration.main(XmlConfiguration.java:1511) ... 7 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.eclipse.jetty.util.TypeUtil.construct(TypeUtil.java:663) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.newObj(XmlConfiguration.java:858) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.itemValue(XmlConfiguration.java:1309) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.value(XmlConfiguration.java:1214) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.newArray(XmlConfiguration.java:936) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.itemValue(XmlConfiguration.java:1313) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.value(XmlConfiguration.java:1214) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.newObj(XmlConfiguration.java:842) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.itemValue(XmlConfiguration.java:1309) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.value(XmlConfiguration.java:1214) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.access$500(XmlConfiguration.java:326) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration$AttrOrElementNode.getList(XmlConfiguration.java:1442) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration$AttrOrElementNode.getList(XmlConfiguration.java:1417) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.call(XmlConfiguration.java:780) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.java:472) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.java:413) at org.eclipse.jetty.xml.XmlConfiguration.configure(XmlConfiguration.java:311) at org.eclipse.jetty.xml.XmlConfiguration$1.run(XmlConfiguration.java:1558) at org.eclipse.jetty.xml.XmlConfiguration$1.run(XmlConfiguration.java:1512) ... 9 more Caused by: java.lang.IllegalStateException: No Server ALPNProcessors! at org.eclipse.jetty.alpn.server.ALPNServerConnectionFactory.<init>(ALPNServerConnectionFactory.java:53) ... 32 more Suppressed: java.lang.UnsupportedClassVersionError: org/eclipse/jetty/alpn/java/server/JDK9ServerALPNProcessor has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:763) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) at java.net.URLClassLoader.access$100(URLClassLoader.java:73) at java.net.URLClassLoader$1.run(URLClassLoader.java:368) at java.net.URLClassLoader$1.run(URLClassLoader.java:362) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:361) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:348) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:370) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:404) at java.util.ServiceLoader$1.next(ServiceLoader.java:480) at org.eclipse.jetty.alpn.server.ALPNServerConnectionFactory.<init>(ALPNServerConnectionFactory.java:60) ... 32 more …and Solr did not start.
