Description Jesse Glick 1999-10-16 00:21:29 UTC 
Thrown from line 312, object2Entry:

 Entry e = entries[hash];

occasionally gives ArrayIndexOutOfBoundsException: -68 or somesuch. Looks like some objects have negative hashCode()s (but not usually??), and hashIt() does not check for this--note that the modulus w
ill return a *negative* value if the hashCode() is negative. To fix, it should be enough to take absolute value of the hashCode or something.
