GB18030 character 龦 can't be parsed by SAXParser

[zhxiaoliibm]

this is the xml file:
GB1803_002.zip

this is the demo code:

         SAXParserFactory spf = SAXParserFactory.newInstance();
         DummySAXEventHandler saxParserHandler = new DummySAXEventHandler();

         try {
             SAXParser saxParser = spf.newSAXParser();
             saxParser.setProperty(XMLConstants.ACCESS_EXTERNAL_DTD, "");
             saxParser.setProperty(XMLConstants.ACCESS_EXTERNAL_SCHEMA, "");
             XMLReader xmlReader = saxParser.getXMLReader();
             xmlReader.setContentHandler(saxParserHandler);
             xmlReader.setEntityResolver(saxParserHandler);
             xmlReader.parse(xmlFileName);
         }
         catch (SAXException e) {
         }
         catch (Exception e) {
         }

when I try to parse this xml file, it will throw an org.xml.sax.SAXParseException with error message

lineNumber: 8; columnNumber: 11; Element type "aBB〢_郎嗀秊_" must be followed by either attribute specifications, ">" or "/>".

Does this need GB18030-2022 support? Support for GB18030-2022 is added in the next release. You didn't mention which version/platform you are using. There are some preliminary builds for the next release available as announced in Slack at https://openj9.slack.com/archives/C01C8PL6319/p1689274282032669, copying the details here.

Semeru Open Edition Milestone 2 build for the July release has been published on a subset of platforms

The support for GB18030-2022 is not in the preliminary jdk8 or jdk20 builds, but will be in the final builds.

I reproduced the failure using Semeru 11.0.20+7 m2 above.
Interestingly, the SAX parser reads the xml file successfully when I replace all the occurrences of the character '龦' (U+9FA6) by '龥' (U+9FA5).

Semeru 17.0.8+6 m2 gives the same result.

The following program gives the same result with 11.0.19, 11.0.20, 17.0.7, and 17.0.8.
Both U+9FA5 and U+9FA6 are defined, and their type is 5 (Character.OTHER_LETTER).

public class CharType {

	public static void showProperties(char c) {
		System.out.println("U+" + Integer.toHexString(c) + ": Type=" + Character.getType(c) + ", isDefined=" + Character.isDefined(c));
	}

	public static void main(String[] args) {
		showProperties('\u9FA5');
		showProperties('\u9FA6');
	}

}

Does it work on a Temurin build? Until the next release is completed, the most recent builds are nightly builds.

Temurin 11.0.20-beta fails in the same way.

Seems the problem, if it is a problem, should be reported to OpenJDK.
