Major 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
