Arne Limburg commented on OWB-872:
----------------------------------
An application may do so, but it's not as easy as adding an observer method to
a bean.
To provide an extension you must implement the
javax.enterprise.inject.spi.Extension interface, create a file
META-INF/javax.enterprise.inject.spi.Extension and put the class-name of your
extension in. Plus you have limited injection-support within such extension.
Please take a look at chapter 11 of the spec for further information.

> Key: OWB-872
> URL: https://issues.apache.org/jira/browse/OWB-872
> Project: OpenWebBeans
> Issue Type: Bug
> Components: Core, Events, Interceptor and Decorators
> Affects Versions: 1.2.0
> Reporter: Christian Schlichtherle
> Priority: Critical
> Attachments: mavenproject1.zip
>
>
> In the attached demo project, the listener method
> {{Main.afterBeanDiscovery()}} suppresses the configured {{@Decorator}} beans.
> As a result, when running the standalone demo, the output is just:
> {code}
> Hello world!
> {code}
> instead of the expected:
> {code}
> ---------- BEGIN PRINT ----------
> Hello world!
> ---------- END PRINT ----------
> {code}
> After commenting out the listener method, the expected output is produced
> again when running the Main class
> {{com.company.mavenproject1.boot.BootWebBeans}}.
