稀奇稀奇真稀奇--使用java Map读取neo4j数据碰到的一个困惑

项目需要，使用neo4j数据库读取XC旅游数据，在写一个方法的时候碰到了一个问题，乍一看逻辑没问题，但是结果是错的，贴上代码一阅：

public List<Map<String,Object>> commentsOfSite(Node sitenode){

List<Map<String,Object>> list=new ArrayList<Map<String,Object>>();
```java
Map<String,Object> comInfo=new HashMap<String,Object>();
```
Iterator<Relationship> relIter1=sitenode.getRelationships(MyRelationship.COMMENT, Direction.INCOMING).iterator();
while (relIter1.hasNext()){

comInfo.put("siteXCID", sitenode.getProperty("XCID"));
Relationship rel1=relIter1.next();
Node comNode=rel1.getStartNode();
Object s_score = null;
Object r_score = null;
Object i_score = null;
int divisor=0;
int score=0;
if(comNode.hasProperty("SIGHT_SCORE")){
s_score = comNode.getProperty("SIGHT_SCORE");
score += Integer.parseInt((String) s_score);
divisor++;
}
if(comNode.hasProperty("INTEREST_SCORE")){
i_score=comNode.getProperty("INTEREST_SCORE");
score += Integer.parseInt((String)i_score);
divisor++;
}
if(comNode.hasProperty("RATIO_SCORE")){
r_score=comNode.getProperty("RATIO_SCORE");
score += Integer.parseInt((String)r_score);
divisor++;
}
if(s_score!=null || i_score!=null || r_score!=null){
int rate= score/divisor;
comInfo.put("rate", rate);
}
else
comInfo.put("rate", "null");
Object comDate=comNode.getProperty("COMMENT_TIME");
comInfo.put("CO
4000
MMENT_TIME",comDate);
Iterator<Relationship> relIter2=comNode.getRelationships(MyRelationship.COMMENT, Direction.OUTGOING).iterator();
while(relIter2.hasNext()){
Relationship rel2=relIter2.next();
Node usernode=rel2.getEndNode();
if(!usernode.getProperty("TYPE").equals("用户"))continue;
Object userXCID=usernode.getProperty("XCID");
comInfo.put("userXCID", userXCID);
}

list.add(comInfo);
}
return list;

}

高亮的地方是问题所在，像上边一样放到while外边的话，输出的list里面的元素一样，只有放到while里面，也就是每次new一个，结果才对

Iterator<Relationship> relIter1=sitenode.getRelationships(MyRelationship.COMMENT, Direction.INCOMING).iterator();
while (relIter1.hasNext()){
```java
Map<String,Object> comInfo=new HashMap<String,Object>();
```
comInfo.put("siteXCID", sitenode.getProperty("XCID"));

前述代码感觉也没有问题，莫非是编译器将字节码优化了？

问题mark一下，敬请指教。
