[jira] [Resolved] (XERCESJ-1532) XMLErrorReporter isn't set in
XMLParserConfiguration when using
org.apache.xerces.parsers.XML11Configuration
[ https://issues.apache.org/jira/browse/XERCESJ-1532?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Glavassevich resolved XERCESJ-1532.
-------------------------------------------
Resolution: Cannot Reproduce
Works for me with the vanilla org.apache.xerces.parsers.XMLDocumentParser. XML11Configuration sets the XMLErrorReporter in its constructor. If this was truly a problem Xerces-J 2.11.0 wouldn't work for anyone, which implies you're either not using the official Apache release (the official binary doesn't have debug info / line numbers) or that com.compumark.util.xni.XNIEncodingDetector is extending Xerces' internals in a way that breaks the configuration.
