8003949: LogManager, downgrade normative reference to ${java.home}/lib/logging.properties

[Paul Sandoz]

Hi Alan,

+ * If neither of these properties is defined then the LogManager uses its
+ * default configuration. The default configuration is typically loaded from the
+ * properties file "{@code lib/logging.properties}" in the Java installation 
+ * directory.

Will typical become atypical for OpenJDK by the time Java 9 ships?

Paul.

This is important as we need the flexibility to eventually move some of these files into module-private locations, maybe in some cases replace them with something else. This is something I've bought up on security-dev and i18n-dev recently as there are number of references to files in ${java.home} that need to be examined.

Clearly this file is changed in some environments, although running with java.util.logging.config.file is probably more robust in that the settings can be used with different JDK installations. The proposed changes (javadoc changes only, no implementation changes) is here:
