[JBoss jBPM] - ERROR: ... CGLIB Enhancement failed ...
by anre42
Hi, i'm just starting up with jbpm and trying to get it to work with my Oracle 10g DB. I've written a small test case just creating the schema, and deploying a simple process but I get "CGLIB Enhancement failed" errors on alot (maybe all) hinernate-mapped classes, see the log below.

| | If you use lazy loading with proxies (default for all classes in Hibernate 3), Hibernate needs to subclass your class at runtime. It can't do this if you have a private no-argument constructor. As per documentation, at least package visibility is required.

|
| I've checked the jbpm code and there are ofcource no "private no-argument constructors", they are all public... so i'm wondering what's going on here? Anoyone has any idea? I have probably missed something but i'm kind of stuck so i'd appreciate all help.

[JBoss Messaging] - Client unable to reconnect to JBoss 1.0.1.SP4 after restart
by bander
Hello, were using JBoss 4.0.4GA with Messaging 1.0.1.SP4.
I've been testing a basic failure scenario where our application is forced to reconnect to JBoss Messaging after experiencing a JBoss connectivity problem.
In theory, when a JBoss connectivity problem is detected (via an ExceptionListener that we set on the jms Connection) we should be able to shut down all our message producers and consumers and recreate them using a new Connection - or at least keep trying to do so until a connection is obtained.
What I'm finding is that about half of the time our producers and consumers can successfully reconnect. Frequently however, they appear to become 'stuck' in the jboss client when attempting to tidy-up after the problem with the Connection is detected. By tidy-up I mean we attempt to close our producers/consumers, sessions and finally the connections themselves - before starting over and recreating everything (i.e. the connection, session etc).
I've written a test case to demonstrate this. What the test case does is spawn two threads. One thread is used for dispatching messages. This thread creates its own connection, session and message producer. The other thread is used for message listening. This thread also creates its own connection, session and message consumer (with message listener). The dispatcher sends messages to the same queue the listener has been configured on.
Before running the test case, configure the queue name to be used.
Note that the test case has a dependency on log4j and commons logging so you'll need those jars handy.
Start JBoss.
When you run the test case, the dispatcher will start sending messages which will be received by the listener.
You should see the following output being repeated over and over:
| 17:39:36,187 INFO @Dispatcher.1 [MultipleServerTest] Dispatcher.1 dispatched message
| 17:39:36,187 INFO @Thread-12 [MultipleServerTest] Listener.1 received message
| 17:39:37,203 INFO @Dispatcher.1 [MultipleServerTest] Dispatcher.1 dispatched message
| 17:39:37,203 INFO @Thread-12 [MultipleServerTest] Listener.1 received message
|
Stop and restart your JBoss server - what *should* happen each time is that dispatcher and listener recover and start sending/receiving messages again. What I'm frequently seeing is that either the dispatcher or listener or sometimes both do not recover. You may need to stop and start the server several times before the behaviour is observed.
The listener/dispatcher threads seem to be getting stuck here:
