SOLR-13030: Close MetricsHistoryHandler inline.
> MetricsHistoryHandler appears to never be "close()ed" - causes thread leaks?
> ----------------------------------------------------------------------------

> Key: SOLR-13030
> URL: https://issues.apache.org/jira/browse/SOLR-13030
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Hoss Man
> Assignee: Mark Miller
> Priority: Major
>
> {{MetricsHistoryHandler}} implements {{Closeable}} and depends on it's
> {{close()}} method to shutdown a {{private ScheduledThreadPoolExecutor
> collectService}} as well as a {{private final SolrRrdBackendFactory factory}}
> (which maintains it's own {{private ScheduledThreadPoolExecutor}} but -as far
> as i can tell nothing seems to every "close" this {{MetricsHistoryHandler}}
> on shutdown.- after changes in 75b1831967982 which move this close() call to
> a {{ForkJoinPool}} in {{CoreContainer.shutdown()}} it seems to be leaking
> threads.
