Reduce redundant log messages: "Narrowing proxy to class xxx - this operation breaks ==" warnings in SessionImpl

My logs are full of "Narrowing proxy to class xxx - this operation breaks ==" warnings. The only way to eliminate the warning is to stop logging of "net.sf.hibernate.impl.SessionImpl" warnings, but it would be better if the problem was resolved within Confluence so that other warnings are not missed because the logging was turned off.
