[Design of Messaging on JBoss (Messaging/JBoss)] - Re: new QueueBrowser implementation

| Whilst, as a temporary measure the queue needs to be copied before browsing, there is no need for this to be exposed on the client or the wireformat, this should just be an internal implementation detail, when creating the browser on the server.
Ok I'll change this.
anonymous wrote : 1) The copy queue was being created using the createQueue method which would also bind it in the post office. This is unnecessary - all we want is a simple in memory copy we can browse
This is so any new messages routed to that address are received by the browser. If we're only bothered about whats in a queue at a certain point in time then We don't need to do it.
anonymous wrote : 2) The queueCopyLock was unnecessary - the list() method on Queue is already synchronized.
Again, this was so no new messages were delivered to the queue after the list method was called.
anonymous wrote : We also need some core integration tests that test the new browsing implementation.
I'm in the process of writing these.

[Design of the JBoss EJB Container] - NPE in JDBCStoreManager
by scott.stark＠jboss.org
With the conf/jboss-service.xml refactoring, I'm seeing the following NPE for some tests (org.jboss.test.hello.test.HelloTimingStressTestCase).

It looks like the EjbModule is starting the pm before the entity container has been started. Why don't we start the pm from the EntityContainer.startService?

I haven't found a solution to this yet.
