Description M.Both 2014-12-17 10:50:20 UTC
Setting the Java system property 
we can see if ClassLoaderLogManager is reading or isn't reading the logging.properties in the class path.
But we don't see if the ClassLoaderLogManager can read the file specified by
Even every exeption is ignored. No information is left.
In my case I wasted many hours to figure out why my logging configuration
does not work. It would be very very helpful seeing an error message
if the file specified by Djava.util.logging.config.file cannot read
by tomcat ClassLoaderLogManager.
