Gary Gregory commented on CSV-184:
----------------------------------
That's not how a HashMap works. Once the map is over its load factory, its
internal size doubles.
For example:
Map m = new java.util.HashMap();
//The map is size() 0 and LF 75% but internally it is size 16.
for (int i = 0; i < 12; i++) {
m.put(i,i);
}
//The map now is size() 11 and the internal size is still < 75% and still
internally size 16.
m.put(12,12);
//The new element puts the map over the LF% so the map now is size() 12 and
internally it doubles to 32.
