It seems that each translator instance can only be used for one translation. This Exception can be avoided if you detach the translator immediately after you use it and renew a different translator for the next translation. A simple demo may like the following:

BaiduTranslator baiduTranslator = new BaiduTranslator();
querierTrans.attach(baiduTranslator);
querierTrans.setParams(LANG.ZH, LANG.EN, source);  
List<String> targets = querierTrans.execute();
querierTrans.detach(baiduTranslator);

for(String target: targets){
    baiduTranslator = new BaiduTranslator();
    querierTrans.attach(baiduTranslator);
    querierTrans.setParams(LANG.EN, LANG.ZH, target);
    List<String> source_ = querierTrans.execute();
    querierTrans.detach(baiduTranslator);
} 

But this solution is rather complicated and time-consuming..

This project is fairly helpful!
But when I tried to translate from A to B and immediately from B to A like this:

querierTrans.setParams(LANG.ZH, LANG.EN, source);  
List<String> targets = querierTrans.execute();
for(String target: targets){
    querierTrans.setParams(LANG.EN, LANG.ZH, target);
    List<String> source_ = querierTrans.execute();
} 

I met the very same issue as shown above.
This problem has nothing to do with which translator I chose. Since I knew few about the HttpClient sort of thing, it's hard for me to understand why this happened.
Thank you.
