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

Applying this patch causes the build to fail.

Maria, could you please try it locally again?

Thanks,

> The method invokeAny in SubjectAwareExecutorService has wrong type. SubjectAwareExecutorService
implements ExecutorService interface.
> ExecutorService:
>     <T> T invokeAny(Collection<Callable<T>> tasks)
> SubjectAwareExecutorService:
>     public <T> T invokeAny(Collection<? extends Callable<T>> tasks)
throws InterruptedException, ExecutionException {
> Reason: It is not possible to override Collection<Callable<T>> tasks with
Collection<? extends Callable<T>> tasks. Such override would not be typesafe.
