Two config items, related to an additional file only based logging for the documentconverter implementation have been removed from the documentconverter.properties.

The documentconverter implementation uses and always used the OX backend standard logging mechanisms ('logback' based nowadays). In addition, it was possible to specify a lightweight, file only based logging via setting the appropriate config items within the documentconverter.properties file.

Since this additional logging frequently caused confusion at the customers, we decided to remove this additional file logging completely and to rely on the standard OX backend logging mechanisms only as with any other bundle.
