[logback-user] Logging uncaught exceptions that go to server.log

[Chris Pratt]

There's an extremely good probability that those statements are being
written to the java.util.logging subsystem.  If you would like those
bridged over to your Logback for processing, look into the SLF4j Bridge
Handler (http://www.slf4j.org/api/org/slf4j/bridge/SLF4JBridgeHandler.html)
