Bug Description:

If the flag LDAP connection flag javax.naming.Context.REFERRAL is set to

Exception in thread "main" java.lang.ClassCastException:

Steps to Reproduce (be specific):
Run the follow test program (attached). You need to change the account
setting. With Java 7 it print 2 numbers. With 8 it print only one number
and then it throw a ClassCastException. The first number is without
"follow". The second which is failing is with "follow".
