14850	NullPointerException on launch (IPv6-checker)	ZeiP	team	"==== What steps will reproduce the problem?

Not sure, this happened when I launched JOSM on Fedora Linux. It hasn't happened before. The computer had no valid IPv6 address at the time, although usually it does.

==== What is the expected result?

==== What happens instead?

==== Please provide any additional information below. Attach a screenshot if possible.
