Class XercesUpdater

java.lang.Object

com.pnfsoftware.jeb.util.format.XercesUpdater

public class XercesUpdater
extends Object

Update some Apache Xerces (XML parser) character tables used by the JDK. Limited to JDK version 8.

The tables do not exactly follow the latest revision of the XML 1.0 specifications, and require tweaking (via reflection hooks) in order to properly parse exotic tag names, eg, using high-value unicode characters.

Note: only the 1.0 table is updated with proper entries for NameStartChar and NameStart
