Subject [jira] [Commented] (SSHD-706) Error: GC overhead limit exceeded after upgrade to 1.3.0
Date Mon, 07 Nov 2016 20:50:58 GMT

    [ https://issues.apache.org/jira/browse/SSHD-706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15645411#comment-15645411

David Ostrovsky commented on SSHD-706:
--------------------------------------

Hi Lyor,

these fixes have fixed the issues! ;-) Tests execution is back to normal, no GC issues any
more.

* da93e0f (HEAD -> master) [SSHD-706] AbstractSession: Cache timeout values initialization
* 38c84a8 (origin/master, origin/HEAD) [SSHD-706] Re-factored the code that invokes the various
listeners to avoid using proxies
* 6c92dcc [SSHD-706] Added more checks if DEBUG/TRACE level enabled before issuing the relevant
log messages
* cac8383 [SSHD-704] No need to wipe string bytes after being placed in the buffer

I'm not sure if "Cache timeout values initialization" diff is really needed, but I had it
in my tree [1].
