I’m trying to build JDK 9 on Ubuntu using Docker. My build hangs at this point:
> Generating java.security > Note: Some input files use unchecked or unsafe operations. > Note: Recompile with -Xlint:unchecked for details. > Warning: generation and use of skeletons and static stubs for JRMP > is deprecated. Skeletons are unnecessary, and static stubs have > been superseded by dynamically generated stubs. Users are > encouraged to migrate away from using rmic to generate skeletons and static > stubs. See the documentation for java.rmi.server.UnicastRemoteObject. How can I can more info to debug the problem? JDK 9 used to build successfully in this environment (maybe 2 months ago). I’m not sure when this started.
