Derp.  Here is the test case:

import java.math.BigInteger;

public class UnsignedLongBug {
   public static void main(String[] args) {
     try {
       String input = "1234567890abcdef1";
       System.out.println(Long.parseUnsignedLong(input, 16));
       BigInteger maxUnsignedLong =
       BigInteger inputValue = new BigInteger(input, 16);
       throw new AssertionError();
     } catch (NumberFormatException expected) {

The Javadoc of Long.parseUnsignedLong specifies that it should throw a
NumberFormatException if "the value represented by the string is larger
than the largest unsigned long, 2^64-1."

This does not appear to be happening:
