This description is not clear enough for users what to do.

In v8.0.5, I ran the following testcase A:

// Test Case A
import javax.xml.parsers.DocumentBuilder
import javax.xml.parsers.DocumentBuilderFactory

/*
System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
	"com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
*/

DocumentBuilder parser = newBuilderInstance()

DocumentBuilder newBuilderInstance() {
	DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance()
	println "This DocumentBuilderFactory is an instance of " + dbFactory.getClass().getName()
	dbFactory.setAttribute("http://javax.xml.XMLConstants/property/accessExternalDTD","")
	dbFactory.setAttribute("http://javax.xml.XMLConstants/property/accessExternalSchema","")
	return dbFactory.newDocumentBuilder()
}

When I ran the Test Case A I got an exception:

This DocumentBuilderFactory is an instance of org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
...

Reason:

This is not good, obviously.

So I changed it slightly as your solution tells us to do. I got the following Test Case B.

// Test Case B
import javax.xml.parsers.DocumentBuilder
import javax.xml.parsers.DocumentBuilderFactory

System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
	"com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");

DocumentBuilder parser = newBuilderInstance()

DocumentBuilder newBuilderInstance() {
	DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance()
	println "This DocumentBuilderFactory is an instance of " + dbFactory.getClass().getName()
	dbFactory.setAttribute("http://javax.xml.XMLConstants/property/accessExternalDTD","")
	dbFactory.setAttribute("http://javax.xml.XMLConstants/property/accessExternalSchema","")
	return dbFactory.newDocumentBuilder()
}

Test Case B worked fine. No exception was thrown. In the console I saw:

This DocumentBuilderFactory is an instance of com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

@duylong,

Do you want us repeat writing our test cases so that they have the line of

System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
    "com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");

in all Test Cases if we are going to process XML document as of v8.0.x? Do you mean it is “a satisfactory fix” done in v8.0.5?

To me, this looks not a “fix”. This is a workaround.

Still it is good to have a workaround for a known problem. If you want users to follow this workaround, then you should write a new page in the official document and explain what users should do clearly.
