问题 I have a very basic JavaFX application that works flawlessly if the Application class is not the Main class: import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.stage.Stage; public class Main { public static void main(String[] args) { Application.launch(App.class, args); } } public class App extends Application { @Override public void start(Stage primaryStage) { FXMLLoader loader = new FXMLLoader(); // works } } However, when I merge the two together (which is

问题 I'm using Java11 and httpclient 4.5.11 to make request to APIs, and so far everything works. But more than a week ago payments to https://api.moip.com.br started giving intermitent errors ( Connection reset ). I know that they require TLSv1.2 and Java11 supports it, furthermore the errors are intermitent (somethimes it works, sometimes it doesn't). I contacted them and they said that they made a migration of their codebase, but that their configuration to process requests is the same, which I

问题 I have a legacy Java (8) project opened in Eclipse with Java 11 (or Java 10). Eclipse is now rightly complaining about inaccessible packages. E.g. com.apple.laf.AquaComboBoxUI . When compiling from command line I can make those packages accessible explicitly by adding a parameter to javac : --add-exports java.desktop/com.apple.laf=ALL-UNNAMED Is there a way to do the same from inside the Eclipse IDE? I tried to add an accessible rule on the JDK library. But that seems to have no effect. Any

问题 When testing the Open JDK 11 HTTP client over HTTP/2, there is a server-side error which looks like a JDK 11 bug. The test runs several threads against a Tomcat 9 server, testing that all threads use HTTP/2 and TLS1.3. The concern is that the error is inside the 'sun.security.ssl.SSLHandshake.produce', which means it is not Tomcat, but the JDK causing the error. Can anyone confirm that you have had the same experience when load testing the HTTP layer of JDK 11? If so, I will reported to the

问题 There has been changes in Java Date & Time API Since Java 9. LocalDateTime now has microseconds precision. Java 9 has a fresh implementation of java.time.Clock capable of capturing the current moment in resolution finer than milliseconds (three digits of decimal fraction). We get the time in microseconds from our backend service. System.currentTimeMillis > 1565245051795 > 2019-08-08T06:17:31.795 Service.getTime > 1565245051795306 > 2019-08-08T06:17:31.795306 In order to construct a

问题 How build GraalVM JVM for Java 11 ? (I don't see any official distributives only java 8) 回答1: Not currently. From this GitHub issue, it seems that it will be ready around the end of February, 2019. However, Java 11 does include support for the Graal compiler, which can be enabled with the following flags: -XX:+UnlockExperimentalVMOptions -XX:+UseJVMCICompiler Edit: According to that GitHub issue, it looks like Graal 19.3 will be released on November 19, 2019, which should include Java 11
