Hi Hoss, Hi, see my other response, this is not the reason why it isn't wrapped:
If i had to guess it's simply because at that time AlreadyClosedException didn't support wrapping any other Throwable. That wasn't added until LUCENE-5958 (circa 2014) which was focused on making sure "tragic" errors kept a record of what caused the tragedy, and then include that as the 'cause' of the AlreadyClosedExceptions throw by 'ensureOpen()'
See my other mail for an explanation, in short: The NPE is only used as signal and not as error condition and MUST be hidden from end user (except for debbugging).
