Result after 2. is attached as 7567.osm.bz2. The first node (id 326106266) of way 44681716 is missing in the output of osmconvert and therefore gives rise to this NullPointerException.

In 5187/josm:

see #7567 - fix NPE with ways with incomplete nodes.

[Don-vip]

The NPE is fixed, but we need to deal with incomplete ways when opening such files. JOSM already detects them, as shown on the standard output:

Le chemin 37 601 755 avec 3 nœuds a des nœuds incomplets car au moins un nœud était manquant dans les données chargées.
...
Le chemin 137 002 879 avec 23 nœuds a des nœuds incomplets car au moins un nœud était manquant dans les données chargées.

I think we should ask to the user if he wants to download incomplete nodes when the file has been loaded.

By the way we were already talking about it in #6761, see this ticket for the next discussions.
