[jira] [Commented] (SSHD-340) Hanging threads

["Ivan Krizsan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SSHD-340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16492475#comment-16492475 ] 

Ivan Krizsan commented on SSHD-340:
-----------------------------------

I am seing hung threads after tests using SshServer in version 1.7.0 with the result that a server instance does not shut down property, causing a "port already in use" error when subsequent test is trying to create a new server.
After having switched to version 0.10.0 the issues are resolved and the server instances shut down properly.

> SSHD fails to stop properly due to errant threads. I've attached a thread dump from a point of execution where everything should have been cleaned up. The hanging threads happen only if the server has accepted connections and they do not hang forever, they seem to stop themselves after a minute or so. This might be an executor pool which is not shut down correctly.
> Earlier versions (0.8.0 and 0.9.0) did not exhibit this behavior.
