Hello,

 Alan (or anyone else), do we have time to discuss these postponed

defects? Or do you have a outlook for this? Thank you.

Hello,

Currently I don't see any patch available so I am trying to create one by myself. I see the problem occurs in AbstractPlainSocketImpl.available() and it seems it is design to return 0 when meed a closed socket - this may not be correct according to the spec, thus change it like this. Would someone review please? I don't think I understand your proposed change as the connection isn't reset in this case. Maybe you meant to change available to check shutrd? In any case, I think we need to be cautious as it would change the behavior for the EOF case and so could cause problems for existing applications. There is also a concern for custom SocketImpl implementations that I mentioned previously. I think that whatever approach is decided on will also require adding clarification to the javadoc. So if it's okay with you, I think we should postpone this to 8. -Alan
