Thanks for the info, one query though ...
Ummm why didn't it just use:
elementData = c.toArray(new Object[c.size()]);
Because "c" might be a concurrent collection, so you
don't want to independently call c.size(). Notice
that AbstractCollection correctly implements
toArray() even for such collections but cannot do so
for toArray(T[] a) because it must interpret
a.length as the required size.
Has that code been updated recently because it sure looks like it tries
to acommodate this and always return an array of exactly size() length
(at the time toArray is called). ??
