I had forgotten our discussion on the PR from 3 weeks ago and had mixed up the outstanding issues; I should have double-checked that. I'll see if I can get a clean run using the updated CFW and we'll go from there.

No problem, I also tend to mix it up when engaging in too many issues/conversations.
Let me know if it solved the issue.
For the record, the referenced PR is - https://github.com/jbossas/jboss-classfilewriter/pull/17

I imagine this happens to you a lot

You wouldn't believe it...
