Hi Steven;
I have updated the patch for Java 8. There's somewhat less code sharing and a
bit of refactoring than your last version but the performance should be about
the same or a little better.

Couldn't you use String(buf, true) for all to(Unsigned)String(...) methods ?
Instead of calculating the mask each time, you could use:
309 private static String toUnsignedString(int i, int shift, int mask) {
Additionally in e.g. Integer.toString(int i, int radix) you could provide the
fast version with:
134 /* Use the faster version */
135 switch (radix) {
136 case 2: return toString(i, 1, 0x1);
136 case 4: return toString(i, 2, 0x3);
136 case 8: return toString(i, 3, 0x7);
136 case 10: return toString(i);
136 case 16: return toString(i, 4, 0xF);
136 case 32: return toString(i, 5, 0x1F);
137 }
