Java logging configuration only partially taken into account

Question

I've an issue with a project I try to deliver using the one-jar packager to simplify the deployment process.
Without the packaging, everything works fine and the logging configuration is perfectly loaded, but within the packaging, only part of the configuration is appied.

So, here is the logging.properties I use:

handlers= java.util.logging.ConsoleHandler, java.util.logging.FileHandler
.level= INFO
java.util.logging.FileHandler.pattern = C:\\MyPath\\logging.csv
java.util.logging.FileHandler.limit = 50000
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = my.package.logging.Formatter
java.util.logging.ConsoleHandler.level = INFO
java.util.logging.ConsoleHandler.formatter = my.package.logging.Formatter

And In my main class, here is how I load it:

public class MainClass {
  public static void main(final String[] args) {
    try {
      LogManager.getLogManager().readConfiguration(
        new MainClass().getClass().getResourceAsStream("logging.properties"));
      // main process goes here.
    } catch(Exception e) {
      // Exception handling
    }
  }
}

The log level as well as the FileHandler pattern are well understood because the logging ends up in the correct file, but as row XML output, which makes me think that the formatter is not loaded as it normally outputs a CSV format.

Could it be related to a classpath issue? Does anyone knows how to handle this?

Answer 1

Use LogManager.getLogManager().readConfiguration(LogManager.class.getResourceAsStream("/logging.debug.properties"));

(note the extra slash).
