Summary: Error messages raised on a class that hasn't changed

Initial Comment:
Not sure why, but these errors seem wrong as the code 
hasn't changed.

I think I know what the problem is now:

> javap -classpath commons-collections-3.0.jar -c
'org.apache.commons.collections.map.AbstractLinkedMap$LinkIterator'
| grep public

public abstract class
org.apache.commons.collections.map.AbstractLinkedMap$LinkIterator
extends java.lang.Object implements
org.apache.commons.collections.OrderedIterator,org.apache.commons.collections.ResettableIterator{
public boolean hasNext();
public boolean hasPrevious();
public void remove();
public void reset();
public java.lang.String toString();
public abstract java.lang.Object previous();
public abstract java.lang.Object next();


> javap -classpath commons-collections.jar -c
'org.apache.commons.collections.map.AbstractLinkedMap$LinkIterator'
| grep public
public abstract class
org.apache.commons.collections.map.AbstractLinkedMap$LinkIterator
extends java.lang.Object implements
org.apache.commons.collections.OrderedIterator,org.apache.commons.collections.ResettableIterator{
public boolean hasNext();
public boolean hasPrevious();
public void remove();
public void reset();
public java.lang.String toString();

Clirr is right, those methods *have* been removed (different
compiler?), but removal of abstract methods should not lead
to an error message if that method is specified by a
superclass / interface.

Forget my comment on return type, I was looking at the
'next' field, not the method...

OK, thanks - I can reproduce this now.

What's even more puzzeling is that the reported return type
is incorrect, judging from the javadocs
AbstractHashedMap$HashIterator.next() returns
AbstractHashedMap.HashEntry, not Object.

Will investigate...

HEAD file too big to attach. Try:
http://cvs.apache.org/builds/jakarta-
commons/nightly/commons-collections/

Javadoc on left (3.0 and HEAD)
http://jakarta.apache.org/commons/collections/

Which versions of commons-collections are you testing
against, and where can I find precompiled binaries and the
javadoc for those versions?
