 * Error: circular dependencies:

(dev-java/openjdk-21.0.1_p12:21/21::gentoo, ebuild scheduled for merge) depends on
 (dev-java/openjdk-21.0.1_p12:21/21::gentoo, ebuild scheduled for merge) (buildtime)

 * Note that circular dependencies can often be avoided by temporarily
 * disabling USE flags that trigger optional dependencies.

Reproducible: Always

Steps to Reproduce:
1. unmerge

1708106715:  *** emerge --jobs=12 --load-average=12.0 --regex-search-auto=y --unmerge =dev-java/openjdk-bin-21.0.1_p12 =dev-java/openjdk-bin-17.0.8.1_p1
1708106721: === Unmerging... (dev-java/openjdk-bin-21.0.1_p12)

3.
Actual Results:  
There was a note while emerging that the bin version of java is not needed anymore. That is in fact not true on this long term installation from 2006.

Please fix portage dependency algorithm. As it is broken as of now.

Expected Results:  
No errors while using portage

Hint please test before making claim that gentoo can build java now from source!
That is strictly false or portage is heavily broken as of now.

Where have you seen that note?
USE=system-bootstrap is forced in profiles/base/package.use.force

I suspect you've masked openjdk-bin or similar which is why you get that.

We'd love a full bootstrap path from source for OpenJDK but you need Java to build Java.
