+== How can I close loggers when using Commons-Logging? ==
+
+You can't. 
+
+Commons-logging is a wrapper intended to isolate code from the underlying logging library when log calls are being made.
+In particular, it is intended to allow library code to contain logging calls without caring about what concrete log implementation
+is being used by the wider application the library is deployed within.
+
+It is not intended to isolate applications from the logging-specific details of initialization and termination.
+
+The fact that some logging implementations auto-configure themselves when first used doesn't mean that commons-logging guarantees to
+do this in all cases, nor that the default initialization behaviour of the concrete logging libraries is appropriate under all circumstances.
+
+And the fact that some logging libraries (or subsets thereof) terminate nicely without requiring library-specific shutdown code doesn't mean that
+all libraries will work correctly in this manner, nor that commons-logging will isolate code from this task.
+
+In short: when necessary, obtain a reference to the actual underlying log implementation and use library-specific calls to initialise
+and terminate as required. 
+
+If you need a reference to the underlying object for a particular commons-logging Log object in order to perform initialisation or
+termination, then in most cases the org.apache.commons.logging.Log class can be downcast to a concrete type that then has a
+"getLogger" method that returns the real underlying object.
