We might want to use a Supplier<BlockInputStream> in the constructor where currently the factory is provided, and then from tests we can provide a TestBlockInputStream, or a mocked InputStream, while in the production code we can just provide a new BlockInputstream from a lambda expression. -- This is an automated message from the Apache Git Service.
