TimeZoneInfo.java的202附近代码如下：
     private static int[] getTransitions(TimeZone tz, long time)
            throws IllegalAccessException, NoSuchFieldException {
        Class<?> zoneInfoClass = tz.getClass();
        Field mTransitionsField = zoneInfoClass.getDeclaredField("mTransitions");
        mTransitionsField.setAccessible(true);
//此处出错
        int[] objTransitions = (int[])mTransitionsField.get(tz);
        int[] transitions = null;
        if (objTransitions.length != 0) {
            transitions = new int[NUM_OF_TRANSITIONS];
            int numOfTransitions = 0;
            for (int i = 0; i < objTransitions.length; ++i) {
                if (objTransitions[i] < time) {
                    continue;
                }
                transitions[numOfTransitions++] = objTransitions[i];
                if (numOfTransitions == NUM_OF_TRANSITIONS) {
                    break;
                }
            }
        }
        return transitions;
    }
