I think the main question here is whether there should be a note in the System.exit and Runtime.exit to document that these methods log? If not, will it be documented anywhere, maybe a troubleshooting guide to help track down what/who is calling System.exit?

Another way to document that could be to add the commented logger name, and  a comment, to https://github.com/openjdk/jdk/blob/master/src/java.logging/share/conf/logging.properties 
A new section at the end with some explanation on what this logger prints and how to enable it - with the appropriate wording to make it clear that it's JDK-implementation specific and not part of the spec.
