wrong logback file used when running from zipped distribution

[jflamy]

When starting with java -jar, the detailed information does not get logged to logs/owlcms.log
For this to happen, using java -cp "classes:owlcms.jar" app.owlcms.Main appears to be required, with a copy of logback.xml in the classes directory. logback.xml is expected on the classpath.

However, when doing this, the log shown on the console appears to be the detailed one, not the summary one without all the details, as if logback-console was in fact being used.
