Sorry Jeremy,
I think I misread your issue.
The issue is that .handlers=X behaves differently than handlers=X
I'm afraid I might have introduced this regression with
https://bugs.openjdk.java.net/browse/JDK-8033661 :-(
The obvious workaround for now would be to use
handlers=
as documented in the logging.properties file.
For compatibility reasons then I think we unfortunately
must continue to support ".handlers" as well, if that
used to work in 8.
I logged https://bugs.openjdk.java.net/browse/JDK-8191033

Hi Jeremy,
Which jdk version/distribution are you using?
I see .level = INFO in the jdk9/master sources:
http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/tip/src/java.logging/share/conf/logging.properties
There should be no changes WRT the default level between 8 and 9.

Hey folks,
I can't find reference to this in a relnote, so I thought I would
ask. If
we have the following files:
logging.properties:
# Set the level of the root logger
.level = INFO
# Send the root logger's output to the console
.handlers = java.util.logging.ConsoleHandler
Test.java:
public class Test {
public static void main(String[] args) {
java.util.logging.Logger.getAnonymousLogger().info("Hi!");
}
}
In Java 8, we will see console output, and in Java 9, we won't.
# Java 8
$ java -Djava.util.logging.config.file=logging.properties Test
Nov 08, 2017 5:02:05 PM Test main
INFO: Hi!
# Java 9
$ java -Djava.util.logging.config.file=logging.properties Test
I thought that, perhaps, a decision was made to have the empty string no
longer mean the root logger, so I took it off of .handlers:
logging.properties:
# Set the level of the root logger
.level = INFO
# Send the root logger's output to the console
handlers = java.util.logging.ConsoleHandler
Success in the sense that this got me output in Java 9. However, .level
still seems to work; if I then have:
# Set the level of the root logger
.level = WARNING
# Send the root logger's output to the console
handlers = java.util.logging.ConsoleHandler
it sets the root logger's level to WARNING.
I don't see any of this in a relnote anywhere, and I don't see an obvious
bug about it anywhere. There seem to have been a fair few changes to
java.util.logging in Java 9. Was a documented decision made to have
.handlers stop meaning handlers on the root logger, but to allow
.level to
continue meaning level on the root logger? Or do I just have the
wrong end
of the stick on this?
Thanks!
Jeremy
