I get a DefinitionException when trying to iterate over an instance of
org.apache.webbeans.inject.instance.InstanceImpl in the current snapshot of
TomEE+ (i.e. in own 1.2.4).
What I am trying to do is:
————————8<————————>8————————
@Stateless
public class JobOperator {
@Inject
private Instance<MyBatchJob> batchJobs;
…
private MyBatchJob findMatchingJob(String jobName) {
MyBatchJob batchJob = null;
for (MyBatchJob job : batchJobs) {
if (job.getName().equalsIgnoreCase(jobName)) {
batchJob = job;
break;
}
}
if (batchJob == null)
throw new RuntimeException("There ain’t no Job named '" + jobName +
"'.");
return batchJob;
}
————————8<————————>8————————
MyBatchJob is a common interface implemented by all my BatchJobs.
When this code is running I get the following Exception:
————————8<————————>8————————
org.apache.webbeans.exception.inject.DefinitionException: Unsupported type null
at org.apache.webbeans.util.ClassUtil.getClazz(ClassUtil.java:950)
at
org.apache.webbeans.container.BeanManagerImpl.getEjbOrJmsProxyReference(BeanManagerImpl.java:804)
at
org.apache.webbeans.container.BeanManagerImpl.getReference(BeanManagerImpl.java:740)
at
org.apache.webbeans.inject.instance.InstanceImpl.iterator(InstanceImpl.java:270)
at
de.nobiscum.rs7030.batch.boundary.JobOperator.findMatchingJob(JobOperator.java:162)
————————8<————————>8————————
I took a look at org.apache.webbeans.inject.instance.InstanceImpl<T> and found
the following:
————————8<————————>8————————
public Iterator<T> iterator()
{
Set<Bean<?>> beans = resolveBeans();
List<T> instances = new ArrayList<T>();
parentCreationalContext.putInjectionPoint(injectionPoint);
try
{
for(Bean<?> bean : beans)
{
T instance = (T)
webBeansContext.getBeanManagerImpl().getReference(bean,null,
parentCreationalContext);
————————8<————————>8————————
It looks like this function is passing null as the beanType to getReference()
which in gets handed down to ClassUtil.getClazz() which chokes on that.
Am I doing something that is not supposed to work here? Or is this a bug?
Should I file a bug report.
Thanks for your help,
