Meet the same issue.

Here is the code:

 
                                                                public static void main(String[] args){
    long nowInMillis = System.currentTimeMillis();
    long INACTIVITY_TOLERANCE_IN_MILLIS = 32L * MILLIS_IN_ONE_DAY;
    RollingCalendar rc = new RollingCalendar("yyyy-MM-dd-HH");
    System.out.println("periodicityType: " + rc.computePeriodicityType().name());
    TimeZone timeZone = rc.getTimeZone();
    System.out.println("timeZone: " + timeZone.getDisplayName());
    long start = nowInMillis;
    long end = nowInMillis + INACTIVITY_TOLERANCE_IN_MILLIS;
    System.out.println("start: " + new Date(start));
    System.out.println("end: " + new Date(end));
    long startFloored = rc.getStartOfCurrentPeriodWithGMTOffsetCorrection(start, timeZone);
    long endFloored = rc.getStartOfCurrentPeriodWithGMTOffsetCorrection(end, timeZone);
    System.out.println("startFloored: " + startFloored + ", " + new Date(startFloored));
    System.out.println("endFloored: " + endFloored + ", " + new Date(endFloored));
    long diff = endFloored - startFloored;
    // will larger than Integer.MAX_VALUE
    System.out.println("diff: " + diff);
    System.out.println("Integer.MAX_VALUE: " + Integer.MAX_VALUE);
    System.out.println((int) diff / MILLIS_IN_ONE_HOUR);

    // Above is the implements of method periodBarriersCrossed(long, long)
    System.out.println(rc.periodBarriersCrossed(start, end));
}
 
                                                            

Here is the output:

 
                                                                periodicityType: TOP_OF_HOUR
