Description
When deploying a kar file into my installation, I get a long list of DEBUG logs like:
16:39:52.095 [DEBUG] [he.karaf.kar.internal.FeatureDetector] - File 'maven-metadata-local.xml' is not a features file.
org.xml.sax.SAXParseException: Premature end of file.

According to KARAF-1198, it seems to be ok to have those files within the kar, so I would expect that the FeatureDetector is also aware of their existence and simply ignore them instead of logging exceptions.
