@soc thanks for your contribution.

Could you adapt with the following changes ?

• I would point to new location of jaxb-api / jaxb-ri github places
• I wouldn't remove the note about mojohaus maven-plugin

Thanks

I would point to new location of jaxb-api / jaxb-ri github places

I feared it would be confusing to link to v3 resources while the plugin only supports v2, but will do!

I wouldn't remove the note about mojohaus maven-plugin

I dropped it because I figured if we can't explain what it is and how it differs from this project, then it will not be helpful to readers either.
Do you have some additional info we can add there?

There's no active branches for jaxb-api v2 / v3 but the latest release are in the new location (https://github.com/jakartaee/jaxb-api/tree/2.3.3)
For jaxb-ri, the EE8 branch points to jaxb-api v2.3.3.

Since the names or now quite identical, pointing to mojohaus' plugin would help user create the issue in the right location in my opinion.

Pushed some changes, moved the link to JAXB to the top to avoid having two links right next to each other, better this way?
