---------------------------------------------------------------------
        Key: AXIS-1369
    Summary: Deadlock in Axis when using HttpClient
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Axis
 Components: 
             Basic Architecture
   Versions:
             1.2 Beta

   Assignee: 
   Reporter: Daniel Marchant

Environment: Solaris 2.8; jdk 1.3.1; httpclient 2.0 rc2

Description:
After running some tests against the Axis client, came across an issue with monitor locking in HttpClient. Researched the issue with the HttpClient and deadlocks and the resolution was to releaseConnection. (reference http://issues.apache.org/bugzilla/show_bug.cgi?id=27434)

While looking through the Axis 1.2 Beta code I couldn't find where it released the connection. 

Possible resolution could be in (org.apache.axis.transport.http.CommonsHTTPSender) line 203 ish to add a wrapper to the Message that would contain the Connection Manager, this way down the chain some other handler can release the connection manager. I'll let you guys work out that kind of detail though :)
