 Description  « Hide

In general, handling of PostConstruct methods for managed beans isn't properly taking into
account method overriding. This works for EJBs, but the implementation needs to be generalized
to handle managed beans as well.

Here's a case that fails:

public class MBBean extends MBBase {
public void postConstruct() {

public class MBBase {
public void postConstruct() {

The postConstruct method will be called twice.

Similarly, if a method hides a PostConstruct method in a superclass,
the method will still be called.

The same issues probably apply to preDestroy methods.

Will look in the future release (not sure who takes the ownership of ManagedBean now (used to be Ken), will keep the issue to me for now).

This problem only exists for ManagedBean when CDI is enabled, e.g., when beans.xml is present. When subclass overrides PostConstruct method with PostConstruct method, it should only be invoked once, but it is currently invoked twice. When subclass overrides with non-PostConstruct method, it should not be invoked as a lifecycle method, but currently it is still invoked.

For PreDestroy, when subclass overrides with a PreDestroy method, it's incorrectly invoked twice. When subclass overrides with a non-PreDestroy method, it is not invoked as expected, but the new PreDestroy method added in subclass is also skipped.

For EJB, all of these cases work correctly, with or without beans.xml.

Thanks Cheng for the analysis. I will let Siva take a look
