Ralph Goers commented on LBCLASSIC-265:
---------------------------------------

I have mentioned this before. Even if there is nothing wrong with the new configuration there is still a timeframe where there is no logging configuration in effect and all logging is disabled.  There is currently no good way to fix this in Logback due to how Loggers and the configuration are co-mingled. This is something I have fixed in my experimental implementation of Log4J 2.0 at Apache.

> When logging with scan="true" it is possible to stop all logging of an application silently.
> Steps to reproduce:
> - start an application with valid configuration and scan=true
> - break the logback.xml (leave out a quote or something)
> -> log goes silent
> Expected behavior:
> Logger fails to load new config and keeps running on the old configuration (like when valid xml, but invalid configuration is loaded).
