Description
int h = hash;
if (h == 0) {
byte[] bytes = this.bytes;
int length = this.length;
for (int i = 0; i < length; i++) {
h = h * 31 + bytes[i];
}
this.hash = h;
}
If this is an empty string, the value of "h" will always be zero, and therefore will not be cached correctly. An empty string will try to re-calculate the hash every time. Instead, make "h" default to 1 to avoid this condition. This change also makes the hash function equivalent to the JDK hash function.
