Subject [jira] [Commented] (HTTPCLIENT-1495) Finalizer in PoolingHttpClientConnectionManager should not log "shutdown" messages if already shutdown normally
Date Tue, 19 Aug 2014 09:09:18 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1495?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14102047#comment-14102047
] 

Christopher Brown commented on HTTPCLIENT-1495:
-----------------------------------------------

I've tested the fix as of 4.3.5, and it seems fine.  No more [Finalizer] thread log messages,
all messages seem to be logged by the expected thread at the expected time.

Thanks.

> Despite shutting down the CloseableHttpClient instance using "close()", which in turn
calls shutdown() on the PoolingHttpClientConnectionManager, messages are still logged such
as the following in all cases after a JVM garbage collection:
> [Finalizer] DEBUG o.a.h.i.c.PoolingHttpClientConnectionManager - Connection manager is
shutting down
> The finalizer thread always calls "shutdown", which always logs the "shutdown" messages.
 This led me to believe (when tracking memory leaks) that there was a problem in my usage
of HTTP client, when in fact the message was just misleading (everything was fine).
> It would be preferable, perhaps via a volatile boolean instance field on the connection
manager, to suppress the shutdown messages (and maybe even suppress redundant resource cleanup
attempts).  This would help users of the library to concentrate on other issues.
> Thanks.
