---------------------------------------------------------------
This bug seems to be a consequence of a change made in tika-1.15 (which still
is contained in newer versions, up to current version 1.24.1)
org.apache.tika.parser.odf,OpenDocumentContentParser
{{@Override}}
public void endElement()
{{ ....}}
{{ if (completelyFiltered == 0) {}}
{{ ...}}{{ }}
{{ } else if ("annotation".equals(localName) || "note".equals(localName)
||}}
{{ "notes".equals(localName)) {}}
{{ closeStyleTags();}}
{{ handler.endElement("", localName, localName); // empty
namespace uri - why?}}
{{ }}}
{{ ...}}
The problem here is the empty namespace string "", which causes a different
handling in
com.sun.org.apache.xml.internal.serializer.ToHTMLStream.endElement():
{{ if (null != namespaceURI && namespaceURI.length() > 0) { // this
condition is not true anymore}}
{{ super.endElement(namespaceURI, localName, name);}}
{{ return;}}
So the fix seems to be as easy as providing a correct namespace uri string in
OpenDocumentContentParser.{{endElement()}}, e.g.:
{{ handler.endElement(XHTMLContentHandler.XHTML}}{{, localName,
localName); }}
