[jira] Commented: (HTTPCLIENT-741) AbstractClientConnAdapter prone
to concurrency issues
[ https://issues.apache.org/jira/browse/HTTPCLIENT-741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12565078#action_12565078 ]
Oleg Kalnichevski commented on HTTPCLIENT-741:
----------------------------------------------
Another major problem is that AbstractClientConnAdapter attempts to release the connection upon invocation of the abort method, which essentially requires the connection manager (or at least its releaseConnection method) to be threading safe. We should not make such assumption.

I am going to go ahead and commit fixes for the above problems, given the fact you may be off-line in the coming days / weeks. Please review the changes when you happen to have a chance. If you find anything disagreeable, please let me know.

> AbstractClientConnAdapter is currently prone to all sorts of concurrency issues. (1) Access to internal state is not properry synchronized making the class prone to race conditions. Presently none of the instance variables is even declared volatile. (2) AbstractClientConnAdapter treats aborted connection as one in an illegal state, which is not quite right.
