Keith Wall commented on QPID-8097:
----------------------------------
Thanks for reporting the problem.
Firstly, let me point out if you are using AMQP 1.0 against Broker-J, use 7.0.0
(7.0.1 should be out in a day or two). Literally scores of AMQP 1.0 defect
fixes - many major - and improvements went into the v7.0.0 line.
Looking at the location of the NPE, I can't immediately see how you reach that
situation. To reach that point in the object's lifecycle, there should have
been a socket which was connected to the remote endpoint. Even if the socket
has been subsequently closed, the {{getNetwork().getRemoteAddress()}} ought to
be returning an {{InetSocketAddress}}. The javadoc says as much [1].

Do you generally have a problem with Broker-J on the OpenJDK (outside of the
tests)? IIRC the differences between Oracle JDK and Open JDK are few. How
exactly are you embedding the Broker?

> Key: QPID-8097
> URL: https://issues.apache.org/jira/browse/QPID-8097
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-6.1.5
> Reporter: Artyom Safronov
> Priority: Major
> Attachments: Qpid stacktrace.txt
>
>
> An unexpected NullPointerException occures in AMQP 1.0 plugin at the first
> attempt to connect to the broker using *OpenJDK*.
> The problem was found while running Qpid in unit tests that verify code
> communicated with the broker through AQMP. There is a test case that starts
> Qpid before each test and stops it after it. That test case verifies a module
> that establishes a connection with the broker. The broker refuses the
> connection because of NullPointerException (see the attached stacktrace).
> Using *Oracle JDK* all tests run fine.
> +The first strange+ thing looks like this. Only a test that does the first
> attempt to connect always fails. The rest tests run successfully although
> Qpid are restarted. So the order of tests is not important. The project is
> built using Maven and all its plugins are run within +a single process+
> (without fork ability).
> +The second strange+ thing is that the behaivor of Qpid slightly differs
> using two different *OpenJDK* versions.
> In a case of *1.8.0_131* version the broker accepts a transport connection
> but rejects "OPEN" frame with the next error:
> {code:java}
> io.vertx.core.impl.NoStackTraceThrowable: Error{condition=amqp:not-found,
> description='Unknown hostname in connection open: 'default'', info=null}
> {code}
> In a case of *1.8.0_161* version the broker rejects a transport connection
> instantly with the next exception:
> {code:java}
> io.vertx.core.VertxException: Disconnected
