NullPointerException when trying to resolve conflict on server during update

[torbjoern.k@…]

During updating an existing dataset, JOSM told me that there is one datapoint, which might no longer exist on the server but locally on my computer.

When I hit "try to resolve on server" I'm getting the following error message (in German):

Daten herunterladen fehlgeschlagen. Das Format ist nicht unterstützt, unzulässig strukturiert und/oder inkonsistent.

Details (nicht übersetzt): java.lang.NullPointerException

As I've run JOSM from command line (with java -jar josm-tested.jar) this is the stacktrace I'm getting:

Replying to torbjoern.k@…:

As I've run JOSM from command line (with java -jar josm-tested.jar)

If you're running tested version, this may be due to #7847. Can you please try with latest ?

[anonymous]

Yes, I've encountered this with the tested version. (sry, I forgot to select it in the bug report)

With the latest version it does work. No error any more. Thanks a lot.
