This used to work in Java 8. final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() { @Override public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException { } @Override public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException { } @Override public java.security.cert

问题 We are using Install4j 7.0.6 and set the Java minimum version to "10.0.1". We are bundling a Java 10.0.1 into the media file. When we replace the included JVM with a Java 9 VM our Application still starts. Are we just missunderstanding the function for the Java minimum version or are we using the wrong version format or is it broken in Install4j 7.0.6? 回答1: The bundled JRE will always be used, regardless of the minimum version. The minimum applies to installed JREs that are checked by the

问题 It's very strange. I am moving a dynamic web project from Java 8 to Java 10. The last thing I cannot get the dependency resolved is the javax.xml.namespace.QName class. You can see in the attached screen shot, the QName class exist in JRE System Library, but the IDE keep complaining that QName cannot be resolved to a type. 回答1: Try to change the order of elements on your classpath. The JRE must be before the Maven Dependencies. That fixes the issue. My guess is that the Java 10 compiler

问题 In the last issue of Heinz Kabutz's newsletter, #255 Java 10: Inferred Local Variables, it is shown that var is not a reserved word in Java 10, because you can also use var as an identifier: public class Java10 { var var = 42; // <-- this works } However, you cannot use i.e. assert as an identifier, as in var assert = 2 , because assert is a reserved word. As it's told in the linked newsletter, the fact that var is not a reserved word is good news, because this allows code from previous

Java 10 allows to do an anonymous class with a var like: var a1 = new Object(){}; var a2 = new Object(){}; But this assignment will throw an error: a1 = a2; jshell> a1 = a2; | Error: | incompatible types: $1 cannot be converted to $1 | a1 = a2; | ^^ Based on the error log, why can't Java 10 assign two inferred var s as an anonymous class to

问题 Following a review of the var feature as seen here: I have encountered difficulties with setting up my Eclipse/IntelliJ IDEA IDEs with JDK 10 and am therefore asking help from Stack Overflow users who have a working Java 10 environment. Consider the following: public class A { public void someMethod() { ... } } public class B extends A{ @Override public void someMethod() { ... } } ... ... ... var myA = new A(); // Works as expected myA = new B(); // Expected to fail in compilation due to var
