-----------------------------------
Summary: Statefull session beans are not (always) properly
destroyed/disposed
Key: AS7-5911
URL: https://issues.jboss.org/browse/AS7-5911
Project: Application Server 7
Issue Type: Bug
Components: CDI / Weld, EE
Affects Versions: 7.1.0.Final
Reporter: Martin Centner
Assignee: Stuart Douglas
Statefull session beans are not always properly disposed when undeploying the application
or stopping the application server.
To reproduce this I've created the following (Arquillian) test.
It contains a simple Java bean:
@Typed
public class TestBean {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
A corresponding producer:
public class TestBeanProducer {
private final Logger log = LoggerFactory.getLogger(getClass());
@Produces
public TestBean produceTestBean() {
log.info("produceTestBean()");
TestBean testBean = new TestBean();
testBean.setMessage("Hello World!");
return testBean;
}
public void disposeTestBean(@Disposes TestBean testBean) {
log.info("disposeTestBean()");
testBean.setMessage(null);
}
}
And finally the statefull session bean:
@Stateful
public class TestStatefullSessionBean {
private final Logger log = LoggerFactory.getLogger(getClass());
@Inject
transient TestBean testBean;
@PostConstruct
public void init() {
log.info("init()");
}
public void test() {
log.info(testBean.getMessage());
}
@PreDestroy
public void cleanUp() {
log.info("cleanUp()");
}
}
When I run this as Arquillian test in the container I get the following expected
behavior:

In our real use case this prevents us from a clean shut down of a Java Content
Repository.
