To reproduce the issue :

use Mustang b70

Please see attached - Test.java , entref01gold.out and Tidy.jar( this is a testutil jar file )
in Test.java - update 'String docURI' to the location where entref01gold.out is saved .

setenv CLASSPATH .:./Tidy.jar
javac Test.java
java Test

error message :
---------------
java Test

fatal error : org.xml.sax.SAXParseException: The entity name must immediately follow the '&' in the entity reference.
line 1 column 1 - Error: <out> is not recognized!
Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.w3c.tidy.ParserImpl._parseHead from class org.w3c.tidy.ParserImpl$ParseHTML
