Thomas Neidhart commented on COLLECTIONS-584:
---------------------------------------------
the load factor is a *parameter* provided to the AbstractHashedMap. If you see
a value like this, your de-serialization code in the derived class is broken.
> Deserializing an AbstractHashedMap expands the hash table exponentially
> -----------------------------------------------------------------------

> Key: COLLECTIONS-584
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-584
> Project: Commons Collections
> Issue Type: Bug
> Affects Versions: 4.1
> Reporter: Diogo Sousa
>
> When deserializing an {{AbstractHashedMap}} the size of the hashtable will be
> doubled at each element inserted because {{threshold}} = 0, so this
> {code}
> protected void checkCapacity() {
> if(this.size >= this.threshold) {
> int newCapacity = this.data.length * 2;
> if(newCapacity <= 1073741824) {
> this.ensureCapacity(newCapacity);
> }
> }
> }
> {code}
> will always expand the hashtable.
