LGTM for me @meonkeys @adamsaghy @vidakovic

FYI.

Changes are minimal compared to dependency bump. and also discussed in dev list.

There are a few more places under fineract-doc/ to update. egrep -ri 'java.+ 21' fineract-doc/src lists these three:

1. fineract-doc/src/docs/en/chapters/development/index.adoc
2. fineract-doc/src/docs/en/chapters/testing/cucumber.adoc
3. fineract-doc/src/docs/en/chapters/testing/integration.adoc

The 1st should be updated, and the 2nd and 3rd ones should be changed to reference (not duplicate) the first, like we do in the readme. One source of truth FTW.

Here's the patch. I can't push directly to the branch so you'll have to apply it yourself (assuming you want it).

0001-update-asciidoc.patch

Apply it locally with git am. No need to squash.

@meonkeys let me try

Should i create a Dedicated Branch for this so that any committer can rebase against develop?

No, just wait. @IOhacker said he'd apply the patch himself.
