Null Pointer Exception while loding custom presets at start - JOSM hangs on splash screen

[Fabi2]

I currently try to write some prsets for the german healthcare system as I encountered this bug.

Snippet from the preferences file:

taggingpreset.sortmenu=true
taggingpreset.sources-list.0=resource://data/defaultpresets.xml.Internal Preset
taggingpreset.sources-list.1=​http://josm.openstreetmap.de/raw-attachment/wiki/Presets/craft-1.xml.Vorlagen für Handwerker
taggingpreset.sources-list.2=/home/fabi/de-hc-preset2.xml.de-hc

This means the internal presets, the craft=* and my own presets should be loaded.

Bug-HOWTO:

1. Activate the presets in the preferences, close JOSM and the make a restart.
2. The error pops up on startup.
3. JOSM hangs on the the splash screen, while "Hauptfenster erzeugen" (creating main window).
4. JOSM must be killed.

In [3839/josm]:

Fix #5893 Null Pointer Exception while loding custom presets at start - JOSM hangs on splash screen

[jttt]

Problem is in your preset, every item and group needs to have name attribute.

Fixed is the NullPointerException and josm should now inform you that name is missing when you add the presets.
