This situation happens when a ContentHandler supplied to the legacy
logger (EventLogger) throws a SAXException. Apparently, it happened
in a call to the characters() method of your TransformerHandler; it is hard
to say anything more definite at this stage.

I suggest to dump the logger output using a plain XML serializer, in order
to see the actual sequence of calls. There is one inside XEP's jar:
com.renderx.sax.Serializer simply dumps its data to the specified file,
stream, or writer. Constructors are:

  public Serializer (String name) throws IOException;
  public Serializer (java.io.OutputStream ostream) throws IOException;
  public Serializer (java.io.Writer writer);

Please set it as the ContentHandler for the EventLogger, e.g.:

EventLogger.logger().setContentHandler(new Serializer("logdump.xml"));

I would like to have a look at the things that end up in logdump.xml;
could you please send me the result off-list?

(A note aside: the XML logging interface is extremely fragile, and it is not easy
for us to maintain well-formedness of the logger event tree. This is the primary
reason we switched to a simple and robust com.renderx.xep.lib.Logger interface
for the new classes: things like this cannot happen there).

Best regards,
Nikolai Grigoriev

Hi,

I got an exception from the event logger, which was set to a default
TransformerHandler. That one just copies the source tree to the result tree.
This is the exception:
