parse-methods now catch Throwable instead of Exception cause of a MethodNotFoundException in Tika. bugfix in Lucene content handler due to consumer thread interruption.
bugfix: some rare deadlock situation inside ToLuceneContentHandler. |  bugfix: nullPointerException in the case some parser invokes a ContentHandler.endDocument() without a succeeding ContentHandler.startDocument(). crawling without startDocument() now works, but there must be at least an endDocument().
