Hi all,
AbstractCollection.toArray(T[] ) might return a new array even if the given array has enough
room for the returned elements when it is concurrently modified. This behavior violates the spec
documented in java.util.Collection .
This patch checks the size of returned array and copies the elements to return to the given
array if it is large enough.
More Questions:
Why don't we have
public <T super E> T[] toArray(T[] a) ?
This would prevent from the cast
r[i] = (T)it.next();
Wouldn't following statement potentially throw a ClassCastException ?
r[i] = (T)it.next();
... but the doc says, it should throw an ArrayStoreException, if the runtime type of the specified
array is not a supertype of the runtime type of every element in this collection.
