    Description

      Hi all, this is not something that hinders the usage of the avro tool but I don't understand why this dependency exists.

      Seems to be more for convenience than anything but for example when I ran the Avro-tool in java I always get this warnings that are a bit annoying.

      It would be great if this could be improved in a future.

      It might just be that there are some hard requirements in other parts of the tool that require this, so in that case this issue makes no sense.

      But I did try to use the util.logging or log4j config files to ignore this warnings but I was not so lucky.

      something like:

      java -Djava.util.logging.config.file=utillog.properties -jar avro-tools-1.11.1.jar getschema avro/person-10.avro

       

      java -Dlog4j.configurationFile=log4j.properties -jar avro-tools-1.11.1.jar getschema avro/person-10.avro
