This is because Unsafe.putByte is used to eliminate array bounds checks, and of course this elimination is safe. In previous versions, in Integer/Long.toString and StringBuilder.append(int/long) scenarios, `-COMPACT_STRING` performed better than `+COMPACT_STRING`. This is because StringUTF16.getChars uses StringUTF16.putChar, which is similar to Unsafe.putChar, and there is no bounds check. ------------- PR Comment: https://git.openjdk.org/jdk/pull/21593#issuecomment-2467068731
