---------------------------------------------------------------
StackLocatorUtil.getCallerClass() walks the stack until it finds the FQCN. It
then skips any stack entries that match the FQCN. It then stops when it has a
stack element that matches the package. That seems wrong. It should be looking
for the first class that doesn't match the package to find the caller. I will
need to create a unit test to verify this is a bug.
That said, I would think this would always result in the wrong class being used
as it should always end up referencing org.slf4j.LoggerFactory.
