The issue is reproducible with version 1.5.3 of an app. However, for the same XWiki instance, the installation log doesn't display any errors or warnings for v1.5.4. As extra info on this issue. Firstly it holds misleading info, whereas on screen it's local XWiki Jetty HSQLDB, and in text it's Standard and MySQL 8.0 (was it configurated instead of HSQL in hibernate properties file or not). Next, last screens with the installation log are related to 1.16-rc2, that version is present in this repository, but it's not listed as Stable Versions (Release Candidate and Stable are two different versions). At least due to these, the issue is invalid and not reproducible with the next version, that's why it shall be closed.

P.S better for future split issues if it's reproduced on another version instead of having one massive issue with screens from different XWiki versions.

[petrenkonikita112263]

Returning to this issue, the SQL warning might raise, is only possible on a local instances with HSQLDB on Windows 10 configurated by default. I've tested locally with Docker instance xwiki:13.10.11-mysql-tomcat and the latest MySQL Docker image mysql-latest. And after that, there's only one warning in Installation log

Still, the same list of warnings on local 13.10 with the latest version of Diagram v1.18.

Plus 2 new ones

[snazare]

licensing errors will be fixed in licensing. We should investigate sql errors if they still appear.

@ane-gabriela could you please let us know if you reproduce the sql errors on 14.10, latest version of the diagram app? thank you!

@snazare Hi! Just tested locally on XWiki 14.10, Chrome 127, Windows 11 Pro
