For External plugin Conflation (not on component menu)

NPE when conflating 2 ways. Action:

1. Copy way from bottom layer to active data layer
2. Select and freeze reference way
3. Select and freeze subject way
4. Conflate

The following output may be relevant:

Also - saw an error when updating plugins. This may be a 1-time error caused by an upgrade migration:

Could not load plugin utilsplugin2 because the plugin main class 'utilsplugin2.UtilsPlugin2 was not found

This plugin is certainly experimental, so there's likely to be bugs like this. I'm in the process of rewriting large portions of this to use the Java Conflation Suite (JCS), which should provide much better functionality (see #7515 for the first step of this).

As to the specific bug report, I can't reproduce it with arbitrary layers, so I'd need example file(s) and a detailed description to thoroughly check this out. Are you actually using this plugin productively, or just trying it out? If the latter, I'll probably close this considering the rewrite. If you actually find this useful already, I'll try and get the bug fixed.

Most code has changed, so marking this as invalid.
