Close open changesets shows stale information

[Ldp]

Open a changeset, upload to it, wait until it's autoclosed (or close from outside the JOSM session). Then go to the Close open changesets menu. It seems to talk to the API to fetch open changesets, but the closed changeset also shows up. Trying to close that pops up the 'already closed' message. Even if you acknowledge that popup, and go to Close open changesets again, that changeset is still shown.

After a long editing session, with lots of changesets, this is what I get:

• "Close open changesets" from the menu
• JOSM performs: GET ​http://api.openstreetmap.org/api/0.6/user/details GET ​http://api.openstreetmap.org/api/0.6/changesets?user=48796&open=true
• JOSM shows 9 open changesets in the dialog (3988087,3987970,3989740,3989038,3987761,3988696,3988893,3989653,3987860)

The actual result when I run the last URL from Firefox:

<osm version="0.6" generator="OpenStreetMap server">
−
<changeset id="3989740" user="Ldp" uid="48796" created_at="2010-02-27T15:55:30Z" open="true" min_lon="5.3255366" min_lat="51.8453671" max_lon="5.4773511" max_lat="51.9267625">
<tag k="created_by" v="JOSM/1.5 (3044 SVN en)"/>
<tag k="comment" v="woonplaatscodes Tiel"/>
</changeset>

<changeset id="3989653" user="Ldp" uid="48796" created_at="2010-02-27T15:47:03Z" open="true" min_lon="5.4880209" min_lat="51.9963843" max_lon="5.5967718" max_lat="52.0628081">
<tag k="created_by" v="JOSM/1.5 (3044 SVN en)"/>
<tag k="comment" v="grenzen Veenendaal"/>
</changeset>
</osm>

Attempting to close any of the 7 actually closed changesets results in an error:

Failed to upload to changeset 3,987,860 because it has already been closed on 2/27/20 2:13 PM.

Doing "Close open changesets" again gives me the same 9 changesets again. So even the one (3987860) for which I got the error isn't removed.

Creating a layer and a single node, then going to the upload dialog, I see the same 9 changesets in the Changesets tab. If I refresh the open changesets from that tab, there is no change either.

Restarting JOSM, then doing "Close open changesets" gives the correct open changesets, as in the API result above.

Replying to Ldp:

The actual result when I run the last URL from Firefox:

The '-' in the output are due to the way Firefox shows XML. They are of course not present in the actual response.

Don't know when exactly this bug has been fixed in the past 6 years, but I cannot reproduce it now.
