JDK-8349637 - Integer.numberOfLeadingZeros outputs incorrectly in certain cases
Description
The test uses counters with this initialization:
    private static int intCounter = Integer.MIN_VALUE;
    private static int longIterations = 100_000_000;

It uses 2 iterations, but misses a counter reset between them.
Timeouts were observed on PPC64.
