@starksm64 I am not sure why this repo is under jakartaredhat in Circle-CI. Any ideas?

It seems the build failure is related to it - it cannot clone the repo with this org assigned.

Can you try to push a commit - I changed the config.

Thanks for this improvement @starksm64. I have just a few questions.

And one little ask in addition - can README.txt be converted to markdown, or better yet, asciidoc? :)

[starksm64]

Ok, CI is back to passing

[bartoszmajsak]

Is it intended to be a support branch with not so many changes in the future or do we expect merging back stuff from ongoing development? If the latter it might be good to think about the approach here (ideally automatic).

[starksm64]

I expect very little ongoing development in this glassfish6 branch.

Merge this PR to upstream glassfish6(not master) branch and release a preview for Glassfish 6.
