NullPointerException at JOSM startup

[Hasienda]

This occures on every startup of josm-latest out of /usr/local/bin since I installed some JOSM plugins. However JOSM and plugins seem to work flawlessly.

the error, JOSM askes me to report here:

I have an older version of JOSM installed from a Debian package build from unstable source (Debian revision: 0.0.0.20080713-1) that throws a java.lang.NullPointerException at startup too, but that one has different wording. Please ask, if that does matter.

[Hasienda]

still valid for revision 1078

Do you have a plugins updated?

What plugins do you use?

[Hasienda]

used to have all of these:
livegps,measurement,namefinder,openvisible,slippy_map_chooser,slippymap,usertools,utilsplugin,wmsplugin,ywms
(copied from ~.josm/preferences)

Update: as of JOSM revision 1082 JOSM won't start anymore, just hangs infinitely in plugin loading step on init

test: with all plugins disabled it starts within secondes as before ... disabling plugins and re-enabling one by one ...

well without error report: livegps,namefinder,openvisible,slippy_map_chooser,usertools,wmsplugin,ywms

checking measurement version 10440: JOSM started, but threw the error I initially reported

	at java.awt.EventDispatchThread.run(EventDispatchThread.java:122)

now JSOM starts within decent time with all plugins again (huh, mysterious ...)

I can reproduce, that disabling measurement plugin fixes the NullPointerException.

marking this as a duplicate, since #1564 already raised an issue with measurement plugin, even category major there, since it crashes JOSM on WinXP

OT: I love Debian GNU/Linux for again being the more robust working environment. :-)
