Closed as duplicate of #7959.
Seems duplicate of #7959

[GerdP]

I can still reproduce this bug with r15820. Should I reopen #7959 or create a new one?

[skyper]

As this is no complete duplicate, how about reopening this one, as there is no milestone set.

Additionally, it should be considered what Donvip on #9951 wrote comment 9:

it could be a good idea to add non-regression unit tests for this feature, as it looks complicated.

and collecting all examples from the different tickets for a complete set.

[GerdP]

I also think that I should add some unit tests before I start to change something. I see so many surprising results ;)

In 15873/josm:

fix #9911: Join areas internal error

• Correct detection and deduplication of nodes with same position
• Add command to remove the detected duplicated nodes if they have no tags and no referrers
