Java's substring() does not copy the text, at least in the official JDK

But, I assume, it will allocate a new instance of String even though the

Yes, but small objects in Java are very fast to allocate and garbage
collect.
It's even faster to not allocate/collect at all! That's the advantage of proper
slices.
