java-11

问题 The following java 11 code: HttpRequest request = HttpRequest.newBuilder() .uri(uri) .header("Digest", digest) .header("Date", date) .build(); gives the following error: Exception in thread "main" java.lang.IllegalArgumentException: restricted header name: "Date" The problem is that the digest is based on the date, so I cannot simply rely on the http client date, because that will make the digest invalid. I need a way to either set the Date header, or to retrieve the Date header and then set

问题 Exit code: 1 - javadoc: error - The code being documented uses packages in the unnamed module, but the packages defined in https://docs.oracle.com/en/java/javase/11/docs/api/ are in named modules.

Edit: This error originated from maven and thrown by the maven-javadoc-plugin. I have not been able to

问题 From inside jShell script, is it possible to access or register variables that are defined in code that's also creating JShell? Currently there seems to be no mechanism to either access or register a variable to Shell instance, or return none string types from inside JShell (like objects or lambda etc.) ex: import jdk.jshell.JShell; import jdk.jshell.JShellException; import jdk.jshell.SnippetEvent; import java.util.List; public class Main { public static void main(String[] args) throws

问题 The HttpClient introduced experimentally in Java 9 is now stable in Java 11, but not surprisingly, very few projects seem to actually use it. Documentation is almost non-existing. One of the most commons asks while making a HTTP call is logging of request/response. How would you do that using the HttpClient , without of course, logging it manually in every single call? Is there an interceptor mechanism like that offered by all other HTTP clients? 回答1: If we look at jdk.internal.net.http

问题 JDK-11 will remove a lot of older parts of the JDK (JEP-320). For some of them (e.g. JAXB) functionality will be provided as regular library. You simply add another dependency and everything works fine again. But not so for CORBA, because There is no significant interest in developing modern applications with CORBA in Java I am however in the painful situation of needing to maintain older applications that still require CORBA while still wanting to update to JDK-11. Is there a replacement
