Subject [GitHub] brooklyn-server issue #409: bump sshj to same jclouds version
Date Mon, 07 Nov 2016 16:43:51 GMT
Github user sjcorbett commented on the issue:

    https://github.com/apache/brooklyn-server/pull/409
  
    I also have integration test failures on this branch:
    ```
      SshjToolIntegrationTest.testAsyncExecAbortsIfProcessFails:273 expected [false] but found
[true]
      SshjToolIntegrationTest.testAsyncExecTimesOut:234 exec took 301 seconds expected [true]
but found [false]
    ```
    In both cases the behaviour actually being tested works as expected but it fails to clean
up temporary files afterwards, blocking on this line of `SshjTool`:
    ```
    int execDeleteResult = asInt(acquire(new ShellAction(deleteTemporaryFilesCommand(), out,
err, pollTimeout)), -1)
    ```
    The tests block waiting for the channel to close:
    ```

    ```
    If you enable sshj's debug log you'll see lots of messages like:
    ```
    DEBUG net.schmizz.concurrent.Promise [main]: Awaiting <<chan#4 / close>>
    ```
