[jira] [Created] (QPID-8097) NullPointerException in AMQP 1.0
plugin using OpenJDK
Artyom Safronov created QPID-8097:
-------------------------------------
Summary: NullPointerException in AMQP 1.0 plugin using OpenJDK
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
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). Under *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 under 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}
