We have a rather important launch tomorrow, and our software uses mina-0.8.1 and SSLFilter.
I have done a lot of stress testing, but the idea that we could possibly get into a deadlock...my boss would kill me

Sorry... should have been 0.9.0-SNAPSHOT

  
Deadlock in SSLFilter
---------------------

         Key: DIRMINA-138
         URL: http://issues.apache.org/jira/browse/DIRMINA-138
     Project: Directory MINA
        Type: Bug
    Versions: 0.8.1
 Environment: Java 5, Linux FC3

    Priority: Blocker
    

  
Found a deadlock in the SSLFilter implementation.  This has happened quite a few times, even with the latest 0.9 snapshots.
This deadlock is causing *all* writes to block, effectively bringing the server to a standstill.
