问题 It's been 3 days that I look on the internet how to fix this on gradle Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXTabPaneSkin (in module com.jfoenix) cannot access class com.sun.javafx.scene.control.behavior.TabPaneBehavior (in module javafx.controls) because module javafx.controls does not export com.sun.javafx.scene.control.behavior to module com.jfoenix On simple idea projects I was adding --add-exports javafx.controls/com.sun.javafx.scene.control.behavior=com

问题 I have a little project which does throw an exception when i let it run. The problem is here (TestObject.java): final JAXBContext jaxbContext = JAXBContext.newInstance(...); I really do not understand why this throws the exception. I also created a test which works like a charm (TestTest.java). Please forgive me the names, but this is just a small test application to get this working with java 11. I followed this: javax.xml.bind.JAXBException Implementation of JAXB-API has not been found on

问题 Currently I'm using tycho to build and package my eclipse RCP app with java 8 and eclipse 4.8, (JMSToolBox) For windows distributions, the tycho build process "copies" the JRE v8 (Oracle) into the distribution package in the "jre" directory via an ant task I'm in the process of upgrading to eclipse RCP 2018-09 and Java 11 (OpenJDK) 2 problems arise: OpenJDK 11 does not provide a JRE OOTB. As I do not want to bundle the 300MB of the full JDK in the distribution, is there a way to embed only

问题 I'm currently migrating some server software from Java 8 to Java 11. Everything works fine except for the fact that TLS connections are refused when my server runs on Java 11 (and only 11). I.e., everything works when running on up to and including Java 10. As soon as I switch to Java 11 (with absolutely no code changes inbetween, of course) I get a TLS decrypt error. My application works fine otherwise when I disable SSL/TLS or when I use IE/Edge to connect to my server (via TLS). When using

问题 I recently learned about JavaFX not being included in Java 11, and have a question about how this will work. Right now, I maintain an application that targets Java 8, uses mostly Swing but some JavaFX, and has a non-developer user base.

问题 Java 11 has added A new instance method isBlank() to java.lang.String class. What's the basic difference between the existing isEmpty and newly added isBlank() method? 回答1: isEmpty() The java string isEmpty() method checks if this string is empty. It returns true , if the length of the string is 0 otherwise false e.g. System.out.println("".isEmpty()); // Prints - True System.out.println(" ".isEmpty()); //Prints - False Java 11 - isBlank() The new instance method java.lang.String.isBlank()
