Catalina warning about javamail.default.address.map

dev

I see this warning in my catalina log file being written constantly:
WARNING [Thread-10161] javax.mail.Session.loadResource expected resource not found: /META-INF/javamail.default.address.map

I saw it mentioned somewhere that this can be resolved by writing an empty javamail.default.address.map file to the META-INF folder, but there IS no META-INF folder anywhere in my installation.

Thoughts?

Thanks!
