Undefined doesn't mean "may crash" in this case, it means that the

Since it is undefined it can crash, but even if it is not, it can
produce the different results for the same application on different cpu.
Definitely. It certainly can crash. There is no way that we should
tolerate UB in any code which is part of Java. We can just use
memmove().
