Description

For the following annotation class in an OSGi bundle

@Retention(RetentionPolicy.RUNTIME)
@Target(

{ ElementType.TYPE, ElementType.METHOD }

)
public @interface Transactional
{
@Nonbinding Class<? extends Annotation>[] qualifier() default Any.class;
}

maven-bundle-plugin fails to generate the package import for javax.enterprise.inject.Any, the default value of the annotation method.

At runtime, this leads to a non-descriptive exception

which is hard to debug.

The problem can be solved by adding an explicit Import-Package element to the plugin configuration, but I don't see why the plugin can't figure this out by itself.

The example is taken from Apache Deltaspike.
