Using IDEA-EAP for JDK9 development experiments. I am getting the following error - Error:(3, 20) java: package jdk.internal.misc is not visible (package jdk.internal.misc is declared in module java.base, which does not export it to module com.jigsaw.npe) The class definition is as - package experiment; import jdk.internal.misc.Unsafe; public class CompareAndSwap { static Unsafe UNSAFE = Unsafe.getUnsafe(); ... } I've tried including a module-info.java file as well inside the module created using the IDE with the following statements - module com.jigsaw.npe { requires java.base; } Directory

The Javadoc tool generates documentation based on the accessibility modifier. By default, it document all public and protected classes, fields and methods. This can be changed with the following options : -public Shows only public classes and members. -protected Shows only protected and public classes and members. This is the default. -package Shows only package, protected, and public classes and members. -private Shows all classes and members. Java 9 introduces the concept of modules, and project Jigsaw applies it to the existing JDK. A talk by Mark Reinhold (3rd in a series of talks about

In JRE-9/lib directory (at least on Windows), there is a new file called modules whose size is about 107 MB. Is it possible to extract that file or maybe list java modules within it? I can see that a new tool called jmod is available at jdk-9/bin/jmod.exe , but that is for reading .jmod files which is located at jdk-9/jmods and it cannot read the file modules . The modules file is a container file. It's internal to the JDK and the format is not documented (it may change at any time). For troubleshooting purposes, the jimage tool in the bin directory can be used to list or extract the contents.

Let's say I have a Java project using Maven 3 and junit. There are src/main/java and src/test/java directories which contain main sources and test sources, respectively (everything is standard). Now I want to migrate the project to Java 9. src/main/java content represents Java 9 module; there is com/acme/project/module-info.java looking approximately like this: module com.acme.project { require module1; require module2; ... } What if test code needs module-info.java of its own? For example, to add a dependence on some module that is only needed for tests, not for production code. In such a

Executing a simple "Hello World" program using Java 9 results in the following error message: Error occurred during initialization of boot layer java.lang.module.FindException: Module com.pantech.myModule not found The command line that I executed was: java --module-path bin -m com.pantech.myModule/com.pantech.myModule.HelloWorld This command line is executed from the parent directory of my bin directory that contains all of the .class bytecode files. The module-info.class file is located in the com.pantech.myModule directory that is located in the bin directory. The HelloWorld.class file
