Michael McCandless commented on LUCENE-1707:
--------------------------------------------
Patch looks good; thanks Shai!
bq. Why is it volatile then?
Good question. Only the ctor (which I believe is fine) and ensureOpen() access
it un-synchronized, so I think we should make it un-volatile; I'll change it
before committing.
bq. What good does "not hiding that bug" do?
EG, say we're working on SegmentReader an accidentally create a bug that
sometimes over decRefs. By no longer throwing an exception on close (with this
change) unit tests might happily pass when previously they would fail and the
bug could go undetected for longer. (Hopefully some tests would still catch
the bug, but maybe not). I think catching a bug sooner rather than later is
better.
Calling close many times is allowed (not a bug), and we handle that by only
doing one decRef. But too many calls to decRef is a real bug and I think we
shouldn't mask/delay it.

> A spin off from here:
> http://www.nabble.com/Excessive-use-of-ensureOpen()-td24127806.html.
> We should stop calling this method when it's not necessary for any internal
> Lucene code. Currently, this code seems to hurt properly written apps,
> unnecessarily.
> Will post a patch soon
