Connections are not properly released causing them to stick in the "CLOSE_WAIT" state and cause
"Too many files open"

                 Key: AXIS2-935
                 URL: http://issues.apache.org/jira/browse/AXIS2-935
             Project: Apache Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: core
    Affects Versions: 1.0
         Environment: Weblogic 8.1.2, Solaris 8 (dont ask!)
            Reporter: Jeff Peterson
            Priority: Critical


It appears that org.apache.axis2.transport.http.SOAPOverHTTPSender does not properly cleanup
the http post connection after payload has been sent.

The symptoms of this problem show up in `netstat` as literally hundreds of connections in
the "CLOSE_WAIT" state.  On a busy server this can cause the application to report exceptions
with the message "Too many open files."

I looked in the source code for axis2 1.0 and discovered that in SOAPOverHTTPSender.java the
releaseConnection() is never called on the postMethod variable.  This seems to be a likely
candidate for the source of the issue.

See SOAPOverHTTPSender.java:97-118
