slf4j with jdk14 is logging INFO messages to stderr

Question

I am trying to get a grip of slf4j with jdk14. Weirdly, some INFO level messages are appearing in stderr.

I am executing the jar with the following command

java -Djava.util.logging.config.file=./src/main/resources/logging.properties -jar ./target/adwordsConnectorV2-account.jar

I am sure that they are INFO level, because when I set the property java.util.logging.ConsoleHandler.level to ALL, the messages show, but when it is set to SEVERE, they don't show.

Please can someone tell me why they might be logging to stderr instead of stdout?

Thanks

Ben

Here is what is logged to stderr:

EDIT: Here is what is in logging.properties:

Can you post logging.properties as well, please? – Boris Jul 21 '14 at 10:51 — Boris, Jul 21 '14 at 10:51

I was seeing messages on stderr because that's the destination used by ConsoleHandler - see the ConsoleHandler javadoc here

The following post shows how to redirect the output, but that is kind of avoiding the problem How do I change java logging console output from std err to std out?

i have decided to switch to log4j instead as recommended by the google adwords team

I started to have the same issue after adding a new dependency (no code changes, no changes to the property file).

This new dependency was transitively pulling in sfl4j, and adding an exclusion in the pom file fixed the issue, as follows:

    <dependency>
      <groupId>org.apache.datasketches</groupId>
      <artifactId>datasketches-hive</artifactId>
      <exclusions>
        <exclusion>
          <groupId>org.slf4j</groupId>
          <artifactId>slf4j-simple</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

slf4j with jdk14 is logging INFO messages to stderr
