Description Jesse Glick 2010-04-01 16:32:19 UTC 
100331.

List<Whatever> l = ...;
l.remove(0); // delete first element

=>

"Given object cannot contain instances of int (expected Whatever)"

which is nonsense since this method overload is remove(int), not remove(Object).

Example in maven/src/org/netbeans/modules/maven/ActionProviderImpl.java:

                if (maps.getActions().size() > 10) {
                    maps.getActions().remove(0);
                }

Comment 3 matthies 2010-12-07 14:31:29 UTC 
It doesn't happen with

    List<String> list = null;
    list.remove(0);


(any more?), but it happens with e.g.


    List<String> list = null;
    list.subList(0, 0).remove(0);
