Just thought I’d follow this up to say that the original PR above was merged in August last year, and the p740 branch currently has the old UUID and anything related to JavaLoader removed to move forward with Java 11 compatibility, plus we have a new mechanism for automatically adding the /jars folder inside a plugin or project to the javaSettings.loadpaths array.
If there are any other CF2018 issues outstanding that anyone has then please let us know. We can back port any fixes that make sense to p720 but otherwise the main branch of new development is currently p740.
