Matt Sicker updated LOG4J2-377:
-------------------------------
Attachment: 0001-Fix-LOG4J2-377.patch
This should fix this bug. The main idea is to load NullConfiguration as soon as
possible so that during shutdown we'll still have an instance to use regardless
of classpath.

> It's a ClassLoader-issue. I guess that log4j2-core uses the
> bootstrap-classloader but not the bundle-classloaer.
