@vnkozlov You I think the patch is now stable, and you can review again.

For the edge-case regressions [here](https://github.com/openjdk/jdk/pull/24278#issuecomment-3213393035): should I file a bug or RFE? At least that way we already are tracking it, and can say we are aware of it if it should ever come up. And we can also provide some possible work-arounds.
