End void rings regression in 26.3 Snapshot-6 due to NaN from int overflow

The End void rings are a documented and intentional terrain generation feature in Java Edition, historically caused by integer overflow in the squared distance calculation leading to NaN values. In snapshot 26w30a, this feature has regressed: the void rings no longer generate at their expected distances. The underlying int overflow still occurs, but the NaN result now causes the entire ring generation to fail instead of producing the intended void ring pattern. This is a regression of a known generation behavior, not a new bug.

Steps to Reproduce

1. Launch Java Edition 26.3 Snapshot-6 in a clean world.

2. Travel to the End dimension.

3. Move to coordinates where void rings are historically expected (e.g., beyond X/Z ±370,727).

4. Launch Java Edition 26.3 Snapshot-5 in a clean world.

5. Travel to the End dimension.

6. Move to coordinates where void rings are historically expected (e.g., beyond X/Z ±370,727).

7. Observe that the void rings are completely absent instead of generating as they have in all prior versions.

Expected Result

The End void rings should generate at their expected distances as a documented terrain feature, consistent with all previous Java Edition versions where this behavior was intentionally preserved.

Actual Result

The void rings are entirely missing in 26.3 Snapshot-6. The int overflow still produces NaN, but the generation algorithm now fails to create the ring pattern instead of rendering it as intended.This is not a bug.
