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:

Is the bug about the add method failing with an ArrayStoreException?

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.

It's there, but not in the documentation for toArray():

| Note that toArray(new Object[0]) is identical in function to toArray().
