When using log4j {} is interpreted as a variable to be replaced by a argument, and since no arguments are supplied the entire message is considered to be an argument. As a result, when a log message should be: binding parameter [2] as [VARCHAR] - [{}] it ends up getting logged as: binding parameter [2] as [VARCHAR] - [binding parameter [2] as [VARCHAR] - [{}]] ( https://hibernate.atlassian.net/browse/HHH-14139#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-14139#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
