Hi Kevin,
That should not be happening. For InputStream Jersey returns -1 as the content length - i.e. does not try to buffer the entity. For the File it reads it using File.length() method.
Are you using any filters in your application? E.g. the logging filter would cause that the entity would get buffered.
