[GNU/Linux] JOSM does not respect LC_MEASUREMENT locale variable

[Self-Perfection]

My current settings are:

$ locale
LANG=ru_RU.UTF-8
LC_CTYPE="ru_RU.UTF-8"
LC_NUMERIC="ru_RU.UTF-8"
LC_TIME="ru_RU.UTF-8"
LC_COLLATE="ru_RU.UTF-8"
LC_MONETARY="ru_RU.UTF-8"
LC_MESSAGES=en_US.UTF-8
LC_PAPER="ru_RU.UTF-8"
LC_NAME="ru_RU.UTF-8"
LC_ADDRESS="ru_RU.UTF-8"
LC_TELEPHONE="ru_RU.UTF-8"
LC_MEASUREMENT="ru_RU.UTF-8"
LC_IDENTIFICATION="ru_RU.UTF-8"
LC_ALL=

And JOSM shows me all distance and speed numbers in feets/miles:

• zoom is measured in feets or miles,
• gpx track segments are measured in feets/miles
• speed in gpx tracks is measured in mph
• etc

But I expect JOSM to use meteres/kilometers, as dictated by LC_MEASUREMENT="ru_RU.UTF-8"! I figured out, that JOSM uses LC_MESSAGES to select both language of UI strings and measurement units. But only strings language should be affected by LC_MESSAGES variable.

JOSM version is 15492

JOSM has own settings for the units. Default is metric. You somehow changed the units. Either change them at map preferences or right click in the status line on the ruler field and select correct setting.

Aha! Found that setting, using it is a good enough workaround for me.

But still in case of missing line <tag key='system_of_measurement' value='???' (as was for me) JOSM incorrectly relies on LC_MESSAGES instead of LC_MEASUREMENT environment variable. This is still a bug, though might be a trivial.

JOSM is always metric on purpose - except for the US. I don't totally agree with this US change Vincent introduced, as defaulting to imperial is nothing I'd like, but I can live with it.

I have the same problem that LC_MEASUREMENT is not respected.
It is another regression of r15395.
Please, use the dedicated environment variable if present.

As en_US is the default language on many linux distributions, the default setting in JOSM did now change to imperial for many users. Could we, please, somehow change this ?
