Subject Clean shutdown (was: OOM with Netty)
Date Sat, 24 Apr 2010 16:52:35 GMT
mmh, as requirement to start/stop james, I would like to read java 1.? 
in the doc :)

Would you agree I open a jira for this (rename shutdown to kill and 
create a clean shutdown).
I could also try to contribute a patch for this.

Tks,

Eric
