Occasionally, we need to rebuild all indexes using the Control Panel.

If there is a problem/bug in a single Indexer (e.g. MediaWikiIndexer as per LPS-19591) then the indexing stops and other content types won't be indexed. In our case, the MediaWikiIndexer bug stops the DocumentLibrary indexer from having a turn.

My proposal is to change to LuceneIndexer#reindex(Indexer) method to catch and log exceptions and then allow the next Indexer to continue, as follows:

    try {
      indexer.reindex(new String[] {String.valueOf(_companyId)});

      if (_log.isInfoEnabled()) {
        _log.info(
          "Reindexing with " + indexer.getClass() +
            " completed in " + (stopWatch.getTime() / Time.SECOND) +
              " seconds");
      }
    } catch (Exception e) {
      _log.error("Reindexing with " + indexer.getClass() + " failed", e);
    }
