Resolution: Fixed
Thanks all for your comments. Robert, I added back maybeReopen to
SearcherManager as deprecated.
Committed rev 1243906 (3x).
Ported to trunk 1244000 (trunk).
I will open a separate issue for SearcherTaxoManager

> I'd like to generalize SearcherManager to a class which can manage instances
> of a certain type of interfaces. The reason is that today SearcherManager
> knows how to handle IndexSearcher instances. I have a SearcherManager which
> manages a pair of IndexSearcher and TaxonomyReader pair.
> Recently, few concurrency bugs were fixed in SearcherManager, and I realized
> that I need to apply them to my version as well. Which led me to think why
> can't we have an SM version which is generic enough so that both my version
> and Lucene's can benefit from?
> The way I see SearcherManager, it can be divided into two parts: (1) the part
> that manages the logic of acquire/release/maybeReopen (i.e., ensureOpen,
> protect from concurrency stuff etc.), and (2) the part which handles
> IndexSearcher, or my SearcherTaxoPair. I'm thinking that if we'll have an
> interface with incRef/decRef/tryIncRef/maybeRefresh, we can make
> SearcherManager a generic class which handles this interface.
> I will post a patch with the initial idea, and we can continue from there.
