Entry for 5.6.14

[jburel]

@sbesson suggested changes included

[sbesson]

Minor stylistic comments but overall this makes more sense to me.

Are we planning to run a minimal test with an artifact built with these changes to ensure it remains compatible with Java 8?

[jburel]

@sbesson done

[jburel]

@sbesson any other comments?

[sbesson]

No other change suggestions from my side. Just the one question around Java 8 testing from #6415 (review) and whether you need anything here?

[jburel]

For the test, I will have to prepare a setup for that and push a release candidate

[jburel]

I pushed to my account a tag including the commits proposed in this PR https://github.com/jburel/openmicroscopy/releases/tag/v5.6.14rc1
I have used omero-install with Java 8 installation and installing the tag.
The server starts and an image is imported see https://github.com/jburel/omero-install/actions/runs/11941208520
