Subject Re: No service reply, after org.xml.sax.SAXParseException; Trying to serialize non-XML 1.0 character:
Date Mon, 21 Nov 2016 21:32:10 GMT
Nelson, a fix for this is part of JIRA UIMA-5189 which addresses error
handing when a serializer throws an exception.
I will post UIMA-AS 2.9.0 release candidate tomorrow so you can test your
use case. Watch for an email on uima dev list.
