Pete Muir closed WELD-445.
--------------------------

         Assignee: Pete Muir
       Resolution: Cannot Reproduce Bug
    Fix Version/s:     (was: 1.0.1.GA)


I wrote a test and couldn't see this problem. I did use a JDK Logger, rather the log4j as I don't have that library available in our testsuite.

If you can reproduce this issue with no external dependencies using the 1.0.1 release (available soon), please reopen :-)
