Max Rydahl Andersen commented on HHH-2218:
------------------------------------------

provide a failing test case then we can see where the issue is.

I run with debug enabled all the time without issues; so something specific in your pojo or mapping is triggering this.

> Similar issues have been logged since May 2005 and have been marked as 'Fixed' by Gavin especially for Session.toString() related cases. However, I am also facing similar issues in Printer.toString()...
> The saving grace is that when I set the debug level to INFO, the problem goes away...
> Am copy/pasting the relevent stacktrace...I have also debugged this on eclipse and the exact location is the call to "new Printer(....)" in AbstractFlushingEventListener.java
