Here's my code: HttpClient client = HttpClient.newHttpClient(); HttpRequest request = HttpRequest.newBuilder() .uri(URI.create("http://127.0.0.1:8081/")) .header("Host", "test.example.com") .build(); client.send(request, HttpResponse.BodyHandlers.ofString()); As a result I see that the above code sends: GET / HTTP/1.1 Connection: Upgrade, HTTP2-Settings Content-Length: 0 Host: 127.0.0.1:8081 HTTP2-Settings: AAEAAEAAAAIAAAABAAMAAABkAAQBAAAAAAUAAEAA Upgrade: h2c User-Agent: Java-http-client/10 Host: test.example.com As you can see it sends two Host headers (the one from URI and the one I

We're planning on migrating our environment from Java 8 to OpenJDK 10. Doing this on my local machine, I've found that Cassandra will no longer start for me, giving the following error : I can't find any solid information online that says it is definitely not supported. This post from 4 months ago suggests that they do not support Java 10, but doesn't say it is confirmed, and is more inferred. There is also a comment on it from another user saying they have managed to get it running on Java 11. The final comment on this ticket on datastax says "We've updated our CI matrix to include Java 10

Previously project is on Tomcat 8 and JDK 8 it was Working Fine But when i migrated my project on Tomcat 9 and JDK 10 it is giving me error as follows : Oct 05, 2018 11:02:01 AM org.apache.catalina.core.ApplicationContext log SEVERE: StandardWrapper.Throwable java.lang.IllegalArgumentException at jersey.repackaged.org.objectweb.asm.ClassReader.<init>(ClassReader.java:170) at jersey.repackaged.org.objectweb.asm.ClassReader.<init>(ClassReader.java:153) at jersey.repackaged.org.objectweb.asm.ClassReader.<init>(ClassReader.java:424) at org.glassfish.jersey.server.internal.scanning

I have code and a test-case in a legacy application, which can be summarized as follows: @Test public void testParseDate() throws ParseException { String toParse = "Mo Aug 18 11:25:26 MESZ +0200 2014"; String pattern = "EEE MMM dd HH:mm:ss z Z yyyy"; DateFormat dateFormatter = new SimpleDateFormat(pattern, Locale.GERMANY); Date date = dateFormatter.parse(toParse); //skipped assumptions } This test passes in Java 8 and below. However with Java 10 upwards this leads to a java.text.ParseException: Unparseable date: "Mo Aug 18 11:25:26 MESZ +0200 2014" . For the record : Besides de_DE , the

I'm reading JEP 317 . It says that Graal (a new experimental Java-based JIT compiler) will be part of JDK 10, but then it says that is already available in JDK 9. So, what's the point of JEP 317 then? Does Java 9 include Graal or not? From one of my memos, on linux-x64 (out-of-the-box) to use Graal on JDK 9, you can enable it using : -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+UseJVMCICompiler Source : Tweet from Chris . If you're explicitly willing to make use of the org.graalvm.* classes, they are not present in the JDK-9 build except for the Linux distribution here and the JEP

This question already has an answer here: Can Java 8 code be compiled to run on Java 7 JVM? 5 answers List of Java class file format major version numbers? 2 answers If I understand correctly the binary form of Java 10 is 100% identical to Java 9 so it shouldn't make any problems. Is my assumption correct? This has nothing to do with Java 10; the rules are the same as they've always been. In every version of Java, the classfile version number has been incremented. You can run older classfiles on a newer Java runtime (you can run files compiled twenty years ago under Java 1.0 on Java 10!), but
