Hi Arjan,

a simple reproducer would be helpful. There are few edge cases around session context and HTTP session which are problematic (e.g. HttpSession.invalidate()).

Do you call some method on the produced Foo before you call destroy? Because in Weld, normal scoped instances are created lazily and so does the HTTP session in case of @SessionScoped.

Thanks,

Martin

Hi,

I have a simple producer:

@Produced
@SessionScoped
public void Foo getFoo() { return new Foo());

If I subsequently want to destroy the Bean using:

Set<Bean<?>> beans = beanManager.getBeans(Foo.class);

Bean<?> bean = (Bean<T>) beanManager.resolve(beans);
Context context = beanManager.getContext(bean.getScope());

((AlterableContext) context).destroy(bean);

Then in Weld 2.3.2 the destroy method of the super class
of org.jboss.weld.context.http.HttpSessionContextImpl is called:

org.jboss.weld.context.AbstractContext

Containing this code:

    @Override
    public void destroy(Contextual<?> contextual) {
        if (!isActive()) {
            throw new ContextNotActiveException();
        }
        checkContextInitialized();
        if (contextual == null) {
            throw ContextLogger.LOG.contextualIsNull();
        }
        final BeanStore beanStore = getBeanStore();
        if (beanStore == null) {
            throw ContextLogger.LOG.noBeanStoreAvailable(this);
        }
        BeanIdentifier id = getId(contextual);
        ContextualInstance<?> beanInstance = beanStore.remove(id);
        if (beanInstance != null) {
            RequestScopedCache.invalidate();
            destroyContextualInstance(beanInstance);
        }
    }

Now the getBeanStore() method
(from org.jboss.weld.context.AbstractBoundContext) returns an
org.jboss.weld.context.beanstore.http.LazySessionBeanStore and this bean
store does *not* contain the Foo bean (no key for its BeanIdentifier).
There are other session scoped beans there that have been instantiated
for the test, but Foo is missing.

If subsequently the session is destroyed, the same destroy method is
called on the
org.jboss.weld.context.http.HttpSessionContextImpl eventually, but now
the getBeanStore() method returns
an org.jboss.weld.context.beanstore.http.EagerSessionBeanStore, and this
one *does* contain the Foo bean.

The other beans that the EagerSessionBeanStore contain are equal to the
ones in the LazySessionBeanStore, the only difference is the Foo bean.

Is this a bug in Weld or am I doing something wrong?

Kind regards,
Arjan Tijms
