[logback-user] Logback NPE in Felix OSGi container.

[Mark Protas]

I'm hitting an NPE in logger initialization in the Felix OSGi container if I
specify the logback.configurationFile system property.  Without the system
property, I don't hit this and everything logs to the ConsoleAppender as
expected.  Any suggestions as to how to fix this?
