Incompatibilities using slf4j 1.6 + with ftpserver-core (1.0)

[Nagesh, Bindu (NSN - IN/Bangalore)]

Hello,
We want to use slf4j 1.6 dependency. We also have ftpserver-core
dependency. It cribs with this slf4j version. Can you suggest which
ftpserver-core version fits well with slf4j 1.6?

Best Regards,

Bindu Nagesh
