AbstractFlushingEvent prints stack trace at ERROR priority
----------------------------------------------------------

          Key: HHH-5407
          URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5407
        Project: Hibernate Core
      Issue Type: Improvement
  Affects Versions: 3.5.4
     Environment: MySQL 5.0.77, Hibernate 3.5.3, Java 1.6.x, Spring, ...
       Reporter: Tony Jacobs
       Priority: Minor


I think my application logic correctly deals with the thrown exception, so I'd like to suppress the stack trace, but I don't want to turn off the ERROR level in a toolkit-level library such as Hibernate. A compromise that we use all of the time at my company is to print a one-liner error message with a hint on how to get the full stack trace for future offenses.

We're running hibernate 3.5.3, but this diff is against an older baseline. The same issue does still appear in hibernate-core trunk (line 324 in the trunk):
