> @jerboaa && @chhagedorn : I'm not familiar with the term "backed out". Does "OpenJDK 11.0.20 in July will have [JDK-8297951](https://bugs.openjdk.org/browse/JDK-8297951) backed out." mean that JDK-8297951 has been reverted?

Hi @KarlHakanNordgren, yes, in OpenJDK 11.0.20, JDK-8297951 is backed out/reverted (see [JDK-8309121](https://bugs.openjdk.org/browse/JDK-8309121)).

There is a REDO task ([JDK-8309119](https://bugs.openjdk.org/browse/JDK-8309119)) which has not (yet?) made it into OpenJDK 11.0.21 but only in OpenJDK 17.0.9.
