I'm sorry but we don't have the manpower to support unmaintained tools. Armintage has not been updated since 2016.
We could make it depend on java 11 though, like hydra
@sbrun is this doable?

Maybe you could make it possible, that armitage will choose the correct java version, when it is started? Otherwise one always has to do an "update-alternative --config java", then chose the correct one - which is annoying.

On the other hand, I do not understand, why it is officially accepted in the repo, when it is buggy. I did not install it from somewhere else, I installed it directly from the kali repo. Please apologize, I do not want to mourn at this point, I am just wondering and would have more expected, that armitage would rather removed or orphaned than left in the repo. Again, this is no mourn!

As you already know, upstream abandoned the project and armitage is no longer maintained. But a lot of users appreciate the tool, just like you :-)
We can't "fork" the project and replace upstream but we are doing our best to fix the issues to keep armitage in Kali.

I have uploaded a fixed version in kali: 20220123-0kali3. Armitage will always use java 11.
The package will be available soon. Please let us know if you still have the problem after the upgrade.

Its working again. Thanks for fixing it!

Best regards

Hans
