> I appears that all methods in {{OpenNLPOpsFactory}} which use a
> {{ResourceLoader}} to get an InputStream to use for building a model are not
> closing those {{InputStreams}}
> This doesn't seem to negatively affect any existing
> {{lucene/analysis/opennlp}} tests, because the JVM doesn't know/care that
> there is a filehandle still open at the end of the test (is there a way to
> make the test complain?) but it does seem to cause a Solr level test failure
> on windows (SOLR-12046) because the solr tests create a temp dir where
> pre-built models are copied for use, and when the test completes the cleanup
> attempts to delete those copies of the files but windows won't let it because
> they are still open.
> presumably if a {{lucene/analysis/opennlp}} test also made a copy of the
> files a similar failure would be triggered -- but only on windows
