public static class MatsFuturizer.MatsFuturizerTimeoutException
This exception is raised through the CompletableFuture if the timeout specified when getting the
CompletableFuture is reached (to get yourself a future, use one of the
futurizeXYZ(..) methods). The exception is
passed to the waiter on the future by CompletableFuture.completeExceptionally(Throwable), where the
consumer can pick it up with e.g. CompletableFuture.exceptionally(Function).
