c.toArray might (incorrectly) not return Object[] (see 6260652) (original) (raw)

So says the ArrayList(Collection) constructor. Can this bug report be opened? Is this workaround still necessary?

I'm confused. The bug states:

 The Collection documentation claims that

     collection.toArray()

 is "identical in function" to

     collection.toArray(new Object[0]);

but I checked the Collection documentation back to 1.4.2 and it doesn't say anything like that as far as I can see.

But as far as I can tell from the code the implementation is unchanged. toArray() will "clone" the internal array and so if you really want Object[] you have use toArray(someObjectArray)
