I only saw this PR after it has been integrated. A code location that
immediately came to mind but was missing in the change is this
java/util/concurrent/SubmissionPublisher.java:1273:
public final void request(long n) {
if (n > 0L) {
for (;;) {
long p = demand, d = p + n; // saturate
if (casDemand(p, d < p ? Long.MAX_VALUE : d))
break;
}
startOnSignal(RUN | ACTIVE | REQS);
}
else
onError(new IllegalArgumentException(
"non-positive subscription request"));
}
Seems like a poster child for the new Math.clamp functionality.
