          Components: AMQP
    Affects Versions: 1.8.0
            Reporter: Krzysztof Porebski
             Fix For: AMQP-1.8.1


There is a problem with creating of nms sessions when connection is not started upfront. The issue reveals itself only in multi-threaded environment. The following integration test can be used to recreate the issue. 


{code:java}
public class NmsSessionTest : AmqpTestSupport
{
    [Test, Timeout(10_000)]
    public void TestCreateMultipleSessionsFromDifferentThreadsWhenConnectionNotStarted()
    {
        Connection = CreateAmqpConnection();
        Assert.NotNull(Connection);

        Parallel.For(0, 10, i =>
        {
            ISession session = Connection.CreateSession();
            Assert.NotNull(session);
        });
    }
}
{code}
 

As a result following exception is thrown:


{code:java}
System.NullReferenceException: Object reference not set to an instance of an object.
