Hi,
Don't know if this is a Bug und if, where to place.
I Use the LazyRealm with CDI to use a Realm from the CDI context of the
Application.
Romain made a Fix to the LazyRealm to address the Situation, where CDI context
isn't present at startup. (thanks @Romain)
Now it's possible to start a TomEE with App deployed. Starting up works correct.
I'm a bit surprised that I reach the "instanc" Function of LazyRealm tree times.
First time:
LazyRealm.instance() line: 106
LazyRealm.initInternal() line: 134
LazyRealm(LifecycleBase).init() line: 102
LazyRealm(LifecycleBase).start() line: 139
è WebBeansContext is Null
Second time:
LazyRealm.instance() line: 106
LazyRealm.startInternal() line: 142
LazyRealm(LifecycleBase).start() line: 150
è WebBeansContext still Null
third time:
LazyRealm.instance() line: 106
LazyRealm.stopInternal() line: 150
LazyRealm(LifecycleBase).stop() line: 232
è WebBeansContext isn't null and bm.getReference returns the correct Bean from
CDI context.
But When TomEE is running and I deploy my webapp then webBeansContext is not
null at first time. Problem is, that bm.getRefereance throws a
NullPointerException than:

I compile my Own LazyRealm simple catch the NPE from bm.getReference and
returning null witch solves the Problem for the Moment:
} else {
final WebBeansContext webBeansContext =
WebBeansContext.currentInstance();
if (webBeansContext == null) {
return null; // too early to have a cdi bean, skip
these methods - mainly init() but @PostConstruct works then
}
final BeanManager bm =
webBeansContext.getBeanManagerImpl();
final Set<Bean<?>> beans = bm.getBeans(clazz);
final Bean<?> bean = bm.resolve(beans);
creationalContext = bm.createCreationalContext(null);
try {
instance = bm.getReference(bean, clazz,
creationalContext);
} catch (NullPointerException npe) {
return null;
}
}
Best Regards
