DOM parser does not honor DocumentBuilderFactory.setExpandEntityReferences(false)

ADDITIONAL SYSTEM INFORMATION :
java version "1.8.0_172"
Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)

A DESCRIPTION OF THE PROBLEM :
This was previously reported as JDK-8025660 and JDK-4762733 but I believe that the resolution was incorrect. Calling DocumentBuilderFactory.setExpandEntityReferences(false) does indeed cause an EntityReference node to appear in the DOM, but a Text node containing the expanded text also appears as the next sibling. This text node is unexpected based on the Javadoc for DocumentBuilderFactory.setExpandEntityReferences.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See test case below. Call DocumentBuilderFactory.setExpandEntityReferences(false) then parse an XML file with an entity reference.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Only the EntityReference node should be present in the DOM
ACTUAL -
The EntityReference node is present, along with a sibling Text node containing the expanded entity value.
