Doing a Debug-Load via Eclipse from Fresh SVN Checkout Throws Errors at Startup: "Error: Unknown projection code"

[alexkemp]

What steps will reproduce the problem?

1. Install latest Eclipse IDE (Oxygen Release Milestone 4 (4.7.0 M4)) under freshly updated Debian GNU/Linux 8.7 (jessie)
2. Checkout SVN under Eclipse into empty workspace dir + load embedded project at josm/core
3. (right-click ▸ Debug as) on "josm/core/eclipse/JOSM (Java 8).launch"
4. It rapidly froze at the Debug screen, and I had to Resume (f8) more than once before JOSM threw up this Report Bug screen

What is the expected result?

JOSM to load to the point of downloading info from server

What happens instead?

JOSM reached 'Setting defaults' & started throwing exceptions

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

Before launching from Eclipse, I had updated JOSM & launched from the latest snapshot + updated all plugins, then exited after startup terminated.

This full, clean update was prompted by an earlier discovery of "Error: Unknown projection code" on similar startup via Eclipse. Cleaning the Build (on this occasion), re-starting Eclipse & then re-doing Debug as (as to be able to report the file + file-line where it first stopped) loaded uneventfully & reached the Start Screen. I'm going to go & lie down in a darkened room again.

Well, I've restarted Eclipse yet again & have debug-launched JOSM yet again & even successfully loaded up a patch of Gedling in the Editor. It seems that I simply needed to shut it down & restart again (I spent 3 years from 1998 telling other folks to do that whilst supporting them on the inter-webs).

I'd like to think that no-one else needed to suffer this, but it also seems that this is a non-defect defect.

Thanks for your attention. Please close this report.

Ant build must be called once before the first run I think.

Run 'ant epsg'
