Ceki Gulcu resolved LBCLASSIC-120.
----------------------------------
Fix Version/s: 0.9.18
Resolution: Fixed
As part of the build, logback bundles are now tested to run with Felix. It is
this assumed that slf4j+logback bundles work with other OSGi containers as
well. Moreover, the tests actually invoke logback configuration via XML.

> When running in OSGi environment, JoranConfigurator throws a
> ClassCastException when trying to parse the Logback XML configuration file.
> The problem seems to be caused by OSGi-unfriendly JAXP parser discovery
> mechanism as suggested by Dieter Wimberger in his blog post --
> http://wimpi.coalevo.net/2008/04/hack-how-to-use-logback.html
> "[...] JAXP discovery mechanism assume visibility of the parser through the
> context ClassLoader of the actual thread, which may cause some troubles."
> Observed exception stack trace:
> Failed to auto configure default logger context
