-----------------------------------

             Summary: Bridge methods treated as observer methods in JDK8
                 Key: ARQ-2042
                 URL: https://issues.jboss.org/browse/ARQ-2042
             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.
