If you are unable to upgrade XML parsers coming from your build logic dependencies, you can force the use of the XML parsers built into the JVM.
For example, in OpenJDK this can be done by adding the following to `gradle.properties`:
```
systemProp.javax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
