Fix #3672

[Certseeds]

fix #3672
in ObjectArrayCodec.java if use PrettyFormat, Do not transferarray id to write(), so it will appear "null"
原有逻辑

for (int i = 0; i < size; ++i) {
    if (i != 0) {
        out.write(',');
        serializer.println();
    }
    serializer.write(array[i]);
}

没有传fieldName过去
现有逻辑

for (int i = 0; i < size; ++i) {
    if (i != 0) {
        out.write(',');
        serializer.println();
    }
    Object item = array[i];
    if (serializer.containsReference(item)) {
        serializer.writeReference(item);
    } else {
        serializer.writeWithFieldName(item, i);
    }
}

PS:
这里serializer.containsReference(item) == false内，改成

Class<?> clazz = item.getClass();
if (clazz != preClazz) {
    preClazz = clazz;
    preWriter = serializer.getObjectWriter(clazz);
}
    preWriter.write(serializer, item, i, null, 0);

是否会有性能提升？

不要引入额外的代码格式化，导致行数更新太多，无法合并
