Conflation Plugin error on conflate

[trvrhldr]

When trying to use the Conflation Plugin, I encountered the error message at the end of this post.

This behavior was found in the some JOSM version, 6767, 6502, 6409, 6296.

The Java was versions 6 and 7.

To avoid contamination from the elements of the map, I downloaded a small extract of the map via JOSM, changed a few street tags and compared the two versions.
