Hi Doug,
I'll create a patch. Is everyone ok with us implementing Map even though we are
technically breaking the contract defined in
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Map.html "An object that maps keys
to
values. A map cannot contain duplicate keys; each key can map to at most one value."
I'm ok with it but wanted to make sure others were prior to creating something.
Matt

Yes, this is a bug.
I think the best way to implement a fix is with a Map from String to
String[], then have an accessor method, get(String), which returns the
first value in the array.
This should probably be a class called Metadata in the io package,
implementing Writable. It could replace Properties in Content and
ParseData. Something like:
public class Metadata implements Map, Writable {
public void add(String, String);
public String get(String);
public String[] getAll(String);
...
}
Does that sound reasonable to you? Would you like to make a patch?
Doug
