ADDITIONAL OS VERSION INFORMATION :
All OS

A DESCRIPTION OF THE PROBLEM :
In wait method you are expecting time in milliseconds and nanoseconds. but in case user pass 0 milliseconds and 1 nano seconds , ideally system should wait maximum 1 nanoseconds but according to current implementation, It'll wait maximum 1000000 nanoseconds.

REGRESSION. Last worked in version 8u121

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Pass 0 as first parameter and 1 in second parameter.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Thread should wait maximum 1 nanoseconds but it'll wait max 1000000 nanoseconds. because inside wait method if nanoseconds b/w 0-999999 , you guys increasing milliseconds 1, that's not correct.

 if (nanos > 0) {
            timeout++;
        }
ACTUAL -
Ideally system should wait max 1 nanoseconds.

REPRODUCIBILITY :
This bug can be reproduced always.
