Please review at your convenience:
Issue: https://bugs.openjdk.java.net/browse/JDK-8069269
Patch: http://cr.openjdk.java.net/~bpb/8069269/webrev.00/
The effective change is line 391 -> 393; the remainder is reformatting.
Consider these hypothetical nanoTime values:
long t0 = Long.MAX_VALUE - 41;
long t1 = t0 + 42;
Ignoring numerical overflow, the second value is mathematically equal to 2^63
which is greater than the first value.
The results of the old and new comparison methodologies applied to the two long
values are:
old:
(t1 - t0) < 0: false
t1 < t0: true
new:
(t0 - t1) < 0: true
t0 < t1: false
This exhibits that the old documentation is incorrect regarding the methodology
to be used when comparing two nanoTime values in the case of numerical
overflow, and that the new documentation is accurate in this case.
Thanks,
Brian
