@Specializes is not compatible with seam-config because of a problem in weld's
BeanDeployerEnvironment
------------------------------------------------------------------------------------------------------
Key: WELD-973
URL: https://issues.jboss.org/browse/WELD-973
Project: Weld
Issue Type: Bug
Affects Versions: 1.1.2.Final
Reporter: Geoffrey De Smet
BeanDeployerEnvironment has 2 methods which - combined with seam-config - break
@Specializes:
{code}
public class BeanDeployerEnvironment {
private final Map<WeldClass<?>, AbstractClassBean<?>> classBeanMap;
protected void addAbstractClassBean(AbstractClassBean<?> bean)
{
...
classBeanMap.put(bean.getWeldAnnotated(), bean);
...
}
public AbstractClassBean<?> getClassBean(WeldClass<?> clazz)
{
if (!classBeanMap.containsKey(clazz))
{
return null;
}
...
}
{code}
Here's what happens:
In this use case I have a bean RepositoryStartupService, which is extra
configured by seam-config.
It is also specialized by TestRepositoryStartupService (for tests).
1) First addAbstractClassBean is called with these parameters:
{code}
bean = Managed Bean [class
org.drools.guvnor.server.repository.RepositoryStartupService] with qualifiers
[@Any @Default @Named]
bean.bean.getWeldAnnotated() = public@Named @XmlConfiguredBean
@ApplicationScoped @XmlId class
org.drools.guvnor.server.repository.RepositoryStartupService
{code}
2) Later on, getClassBean is called to find the parent class
RepositoryStartupService:
{code}
clazz = public@Named @ApplicationScoped class
org.drools.guvnor.server.repository.RepositoryStartupService
{code}
which returns null because the @XmlConfiguredBean bits are missing.
So I get this exception message:
{code}
org.jboss.weld.exceptions.DefinitionException: WELD-000047 Specializing bean
must extend another bean: Managed Bean [class
org.drools.guvnor.server.repository.TestRepositoryStartupService] with
qualifiers [@Any @Default]
{code}
One can argue that since seam-config is not configuring
TestRepositoryStartupService a failure is normal,
but *even in that case the exception message is very misleading*, as looking at
the code TestRepositoryStartupService clearly extends RepositoryStartupService
which is also a bean.
