> Common collections 3.1 and 3.2 are used at many places and frameworks 
> including struts2. 
> Supose a LinkedMap object it is created and have size greater than zero is 
> serialized. While deserializing this object , array of HashEntry naming data 
> delacred in AbstractHashedMap always initialises with a new capacity of 
> double its double of the serialized object. 
> Please see the below API declared in AbstractHashedMap class :
> {code:java}
> protected void checkCapacity()
>   {
>     if (this.size >= this.threshold)
>     {
>       int newCapacity = this.data.length * 2;
>       if (newCapacity <= 1073741824) {
>         ensureCapacity(newCapacity);
>       }
