New Revision: 1602159
URL: http://svn.apache.org/r1602159
Log:
https://issues.apache.org/bugzilla/show_bug.cgi?id=56546 (very partial)
Reduce verbosity of clear references logging. Although it is a good tool for
detecting leaks, the severity does not match the likely impact. Also avoid
having more than one logging for one event even if filtering becomes less
flexible.
