`Xpp3DomBuilder.createXmlReader()` (lines 119-129) clears and restores the global `org.xml.sax.driver` system property without synchronization. In a multi-threaded environment (like Maven parallel builds), one thread's clear/restore sequence can interfere with another thread's read or write of the same property. The code even acknowledges this with the comment: "There's a 'slight' problem with this an parallel maven: It does not work ;)" The method already tries to directly instantiate `com.sun.org.apache.xerces.internal.parsers.SAXParser` first (line 114), which succeeds on all Oracle/OpenJDK JVMs. The system property manipulation fallback is both unnecessary and harmful. Fix: remove the system property manipulation. If the direct instantiation fails, just call `XMLReaderFactory.createXMLReader()` without modifying any system properties. -- This is an automated message from the Apache Git Service.
