Extra logging by unknown source logger

[Hoa Phan]

Hi I noticed when I set:

org.apache.tomcat.util.scan.StandardJarScanner = SEVERE

I still get similar msg from a strange logger(no "org.apache" in the logger
name):

build 11-Jun-2017 13:37:24 localhost-startStop-1 WARN
 [tomcat.util.scan.StandardJarScanner] Failed to scan
[file:/.../common/lib/p6psy.jar (No such file or directory)

Anyone know where this comes from? How can I configure it?

Thanks.

Hoa Phan.
