Hi I noticed both IndexReader and IndexWriter call ensureOpen in almost every method. How critical is this check? Why would someone call any of these when the writer or reader are close?
If we add isOpen() to both, then I think we can remove this code from IndexWriter/Reader, and tell folks to use it if they don't know whether the instance they have in hands is open or close before they call any other method. What do you think? I can patch it up. Shai
