Found shared references to a collection hibernate

 Today when i was working on my project i saw a very strange bug saying "Found shared references to a collection hibernate" with a long stacktrace. After wasting a long time browsing through different sites. I started seeing the code, there i found a very small thing which solved my problem and it was that i initialized the variable before starting FOR loop and was trying to add multiple objects of the same memory reference again and again. For e.g.

ArrayList list = new ArrayList();
String str= new String("test");
for(int i=0; i
    list.add(i);
}
here you will get the same Found shared references error. Therefore i simply brougth the initialization into the FOR loop and it got resolved
