A DESCRIPTION OF THE PROBLEM :
The issue described in JDK-6770436 also occurs for non-predefined entities.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use a DefaultHandler2, register lexical-handler, and parse this document:

<!DOCTYPE x [<!ENTITY e "v">]><x>&e;</x>

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
startEntity: e
characters: v
endEntity: e
ACTUAL -
startEntity: e
endEntity: e
characters: v
