NPE XHTMLContentHandler in characters Method
--------------------------------------------
Key: TIKA-760
URL: https://issues.apache.org/jira/browse/TIKA-760
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 0.10
Environment: JDK 1.6, Linux
Reporter: Torsten Krah
The method:
public void characters(String characters) throws SAXException {
characters(characters.toCharArray(), 0, characters.length());
}
does not check for null values.
On many code references a check is done "before" calling this methd. However on
other sides, e.g. HSLFExtractor some values are not checked:
xhtml.characters( comment.getAuthor() );
which may be null.
The simplest fix would be to check for null on the handler and if it is null
handle it as NOOP or insert the new UTF-8 "replacement char" to let the user
decide.
