Therefore I propose to amend LoggerFactory to contain an optional reference to StaticLoggerBinder instance, which (when non-null) would be used instead of normal StaticLoggerBinder.getSingleton(); therefore this overriding instance could reside in different package. It would suppress checks for multiple binders as well. -- This message was sent by Atlassian JIRA (v7.3.1#73012)
