Why isn’t this handled automatically when moving a project from a previous JDK(10 to 12)? I would think especially when doing a Clean & Build using the latest version of the IDE(10.0 to 11.1).
I’ve just recently begun using an IDE and have experienced several similar problems that I think should be handled by NetBeans. I expect problems like this when using the command line. warning: [options] bootstrap class path not set in conjunction with -source 10 1 warning Best Regards, Michael
