Oliver Heger commented on CONFIGURATION-627:
--------------------------------------------
I don' t think there is anything to fix in Commons Configuration.
BeanUtils's {{FluentPropertyBeanIntrospector}} scans classes for property
access methods. If it encounters a set() method whose signature is not
compatible with a property setter method, it issues this log message. When
applied on a Configuration object this happens for the _setProperty()_ method
(which obviously cannot be renamed).
The original bug report was that an exception stack trace on level WARN was
logged. This has been changed to a message on INFO level which might be useful
for diagnostic purposes. (I am not sure whether a low-level library like
BeanUtils actually needs logging, but so is the current implementation.)
Do you mean this INFO message is still a problem?
