The following used to work in JDK 8:

logging.properties:
==============
.level = INFO
.handlers = java.util.logging.ConsoleHandler
==============

Test.java:
public class Test {
    public static void main(String[] args) {
      java.util.logging.Logger.getAnonymousLogger().info("Hi!");
    }
}

but no longer woks in 9. In 9 you have to write:

logging.properties:
==============
.level = INFO
handlers = java.util.logging.ConsoleHandler
==============

(as specified in logging.properties)

This is a regression, probably introduced by JDK-8033661
