Upload was slow, then canceled, then JOSM threw an exception

[grigory.rechistov@…]

What steps will reproduce the problem?

1. Make a change, try to upload it
2. The upload appears to be stuck because of a slow network, so press the Cancel button once or twice
3. Try to upload again, and JOSM threw a exception
4. Ignoring and continuing does not lead to additional strangeness, so far.

What is the expected result?

What happens instead?

Please provide any additional information below. Attach a screenshot if possible.
