I suggest using the enclosed patch, which allows the build to succeed by
overriding the ``test'' method of Predicate<T>. The ``apply'' method
provided by upstream has to be kept as it is used by the ``test'' method.
The definition in the patch is the same as in Predicate<T>. ``test'' is
a default method in the interface Predicate<T>, I thus don't see why it
needs an override... Nevertheless, this fixes the issue.
