>             Project: Arquillian
>          Issue Type: Bug
>          Components: Base Implementation
>    Affects Versions: 1.1.11.Final
>         Environment: JDK 8
>            Reporter: Bartosz Majsak

> The Java Compiler was changed with regards to synthetic methods and Annotations.
> Before, annotations on parameters of the original generic methods were NOT copied on to the synthetic bridge method.
> Now, the original annotation is present in 2 places: the generic method (with the actual type replaced in place of the type parameter) and the synthetic method.
> When it comes to the @Observes annotation, Arquillian will try to call the synthetic method (which receives Object) with any kind of event, leading to a ClassCastException (because the bridge method does an implicit cast to the actual type and calls the real generic method)
> The commit makes Arquillian ignore synthetic methods when searching for potential event listeners.
