Summary | 0005487: issue 5239 is not fixed .ArrayIndexOutOfBoundsException | |||||||||||
Description |
issue 5239 is not fixed int hash = System.identityHashCode(key) % prime; can return negative integers 1. because ibm sdk 1.6 AIX can give negative identityHashCode 2. because java returns negative modulo result for negative first operand addition: if (hash < 0) { hash += prime; } guarantees >=0 integers (and maintains modulo) |
