[weld-issues] [JBoss JIRA] (WELD-1131) Weld Proxies (for instance created by Producer-Method) loose Annotations put ontop of Methods of source class
[

P Huber commented on WELD-1131:
-------------------------------
This is the original Annotation which has Retention "Runtime" from the begining
(but good you've asked...I admittetly forgot that in the past on several occasions
;-)
@Target({ METHOD, FIELD })
@Retention(RUNTIME)
@Documented
public @interface PredicateDef {
String value();
}
And the use of it is
@PredicateDef("...")
public String getFirstName() {
return firstName;
}
And I found a workaround in the meantime which works for me
I had used this, which *does NOT* work:
final BeanInfo bi = Introspector.getBeanInfo(selectedCustomer.getClass());
and replaced it with this *working* version:
final BeanInfo bi =
Introspector.getBeanInfo(selectedCustomer.getClass().getSuperClass());

Arquillian: I'm not yet into Arquillian, but I can try to do a simple sample with
standalone WELD CDI. It guess it should be possible to mimik the issue, though I cannot
promise.
Weld Proxies (for instance created by Producer-Method) loose
Annotations put ontop of Methods of source class
-------------------------------------------------------------------------------------------------------------
Key: WELD-1131
URL: https://issues.jboss.org/browse/WELD-1131
Project: Weld
Issue Type: Bug
Components: Reflection layer
Environment: glassfish 3.1.2
Reporter: P Huber
I have project specific Annotations ontop of public Methods of a class.
class Customer {
@MyProjectSpecificAnnotation
public String getFirstName() {
return firstName;
}
}
When producing Objects of such an annotated class, like with
class Example {
@Produce
Customer producerField;
}
Then at the Injection Side the Annotations "MyProjectSpecificAnnotation" is no
longer available, because WELD injects a byte-code created proxy.
class InjectionSide {
@Inject
Customer injectField; // here we get the WELD-Proxy of unpronouncable name...and no
Annotations
}
I've used BeanIntrospector to reflect the injected Instance of class Customer. I get
a set of PropertyDescriptors with a write/read Method each.
But as allready said, none of them has the "MyProjectSpecificAnnotation".
Could be due to the fact, that when subclassing a class, the Annotations of the super
class are not available at sub class directly - But in Case of a "transparent"
WELD proxy I'd expect they should be there. Probably you have to simply copy
annotations during on-the-fly byte-code creation of the Proxy. The Problem is btw also
true for javas built in Dynamic Proxy: using it you also loose Annotations.
Hope you can fix that
