> Key: OWB-1004
> URL: https://issues.apache.org/jira/browse/OWB-1004
> Project: OpenWebBeans
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.5.0
> Reporter: Antonin Stefanutti
>
> While having multiple annotations of the same type declared on a member or
> type is not permitted in the Java language prior to Java 8, the CDI
> specification does not set any particular restriction in its SPI that enables
> to alter bean metadata, e.g. in {{Annotated.getAnnotations()}} and
> {{BeanAttributes.getQualifiers()}}, in a way to add multiple annotations of
> the same type.
> Having multiple CDI qualifiers of the same type can prove to be useful when
> this type declares binding attributes.
> Unfortunately, in such situation, the following exception is thrown by OWB
> version 2.0-SNASHOT:
> {code}
> javax.enterprise.inject.spi.DefinitionException:
> java.lang.IllegalArgumentException: Manager.resolveDecorators() method
> parameter qualifiers array argument can not define duplicate qualifier
> annotation with name : @org.apache.camel.cdi.ContextName
> at
> org.apache.webbeans.config.BeansDeployer.deploy(BeansDeployer.java:284)
> at
> org.apache.webbeans.lifecycle.AbstractLifeCycle.bootstrapApplication(AbstractLifeCycle.java:138)

> {code}
> IMO, preventing the ability to add multiple annotations of the same type via
> the CDI SPI restricts powerful use cases (I can share more details on these
> use cases if needed). Last but not least, having this ability built-in in the
> Java 8 language is another incentive to provide that support.
