Publish with SSH (sftp or ssh) prevents enclosing java process to terminate
---------------------------------------------------------------------------

                 Key: IVY-1075
                 URL: https://issues.apache.org/jira/browse/IVY-1075
             Project: Ivy
          Issue Type: Bug
    Affects Versions: 2.1.0-RC1
         Environment: buildr 1.3.4 running on jruby 1.2.0 with latest jsch-0.1.41 jar
            Reporter: Klaas Prause


We try to add ivy support to buildr. Buildr comes with an AntWrap gem to call Ant targets
from within a buildr script:
1. using a standard publish via Antwrap using the same parameters that work in Ant
2. the publish works all artifacts are copied and the buildr script continues till its end,
but the buildr java process does not terminate!

when publishing to a local repository the process terminates fine, so it has something to
do with the SSH connection.
using lsof and checking the open file handles the process has an open connection to the repository
via SSH and some other open sockets (lsof output for process):
[...]

I checked out the source but could not find the problem. My best guess is that the last SSH
connection is cached within SshCache and never disconnected from Ivy.

This is a blocker to change from ANT to Buildr, because the build scripts do not terminate
normally so they cannot be used in the integration server.

We have the same problem with an hanging jruby script using Ivy not via Ant but via the Ivy
class to resolve projects. The Ivy class is instantiated from within JRuby and used to resolve
ivy.xmls to get some information about projects. The script does not terminate after a resolve
against a remote repository using SSH has been done.
