Commons-logging

[Charles Givre]

Hello Drill Devs, 
I am working on submitting some UDFs, and in so doing discovered that one UDF 
has a dependency (commons-validator) which itself has a dependency of 
commons-logging which is banned. Does anyone  know why commons-logging is 
banned?   I’m not a maven expert but is it possible to exclude the 
commons-logging dependency somehow so that we could use commons-validator in 
Drill?
Thanks,
