JAXB + SAX + Open JDK 8 Getting Connection Reset by Client Exception

Question

My code downloads XML report from net and assigns the raw XML to a String variable. It then creates a SAXPaser like so:

try {
             SAXParserFactory spf = SAXParserFactory.newInstance();
    
             spf.setXIncludeAware(true);
             spf.setNamespaceAware(true);
             spf.setValidating(true); // Not required for JAXB/XInclude
    
             XMLReader xr = (XMLReader) spf.newSAXParser().getXMLReader();
             xr.setFeature("http://apache.org/xml/features/disallow-doctype-decl", false); //with true report could not be parsed
             xr.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false); // This may not be strictly required as DTDs shouldn't be allowed at all, per previous line.
             xr.setFeature("http://xml.org/sax/features/external-general-entities", false);
             xr.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
             return new SAXSource(xr,  new InputSource(new StringReader(output)));
        } catch (Exception e) {
            e.printStackTrace();
        }

It then calls jaxb method to unmarshal the XML like so

jaxbUnmarshaller.unmarshal(saxSource);

This triggers the following exception. Looked up the class in docs and "ClassLoader:null"

factoryClassName - fully qualified factory class name that provides implementation of javax.xml.parsers.SAXParserFactory.

classLoader - ClassLoader used to load the factory class. If null current Thread's context classLoader is used to load the factory class.

I saw advice given by others on SOF that said don't use "com.sun" packages. Unfortunately I have to use Java 8, specifically:

openjdk version "1.8.0_392"

The code behind the exception worked with Oracle Java 8 as far as I know. I will appreciate any help.

Thank you
