Subject [jira] Commented: (QPID-1782) Java client sporadically times out trying to create a connection
Date Tue, 31 Mar 2009 16:14:50 GMT

    [ https://issues.apache.org/jira/browse/QPID-1782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12694167#action_12694167

Aidan Skinner commented on QPID-1782:
-------------------------------------

I suspect that the problem is in this block of Connection.connect:

            IoTransport.connect(host, port, ConnectionBinding.get(this), ssl);
            send(new ProtocolHeader(1, 0, 10));

            Waiter w = new Waiter(lock, timeout);
            while (w.hasTime() && state == OPENING && error == null)
            {
                w.await();
            }

            if (error != null)
            {

What I think is probably happening is that the call to exception() occurs right after the
check, but I can't prove this. The exception that's thrown shows that it never gets out of
the OPENING state.

> Some tests will randomly throw these errors when run against the Java broker. Most of
the time they will succeed, both immediately before and immediately after one of those failures.

with that code so far.
