Hi Someone ran into this in the context of working with TeeSinkTokenFilter - when the state is cloned for each of the sinks, if you have a PayloadAttribute on the stream, it's shallow cloned and thus all sinks share the same byte[].
At first I thought this is just a bug in PA.clone(), and that it should have been implemented using deepCopyOf, but then I noticed that it's actually documented that if you require deep cloning, you should implement your own PA (or at least override .clone()). But then, CharTermAttribute.clone() documents that it does a shallow clone, but actually implements a *deep* clone. So now I think PA.clone() should indeed be implemented as a deep clone... What do you think? Shai
