[logback-dev] Unit test hangs.

7 Sep 2009

      While testing my changes to logback I ran into a bit of a problem with  
one of the unit tests.  
ch.qos.logback.classic.net.SMTPAppender_SubethaSMTPTest hangs every  
time i run it. I even downloaded from your repository and tried it  
with the same results.  This is on my MacBook Pro.

Output from jstack.
