These flags are deprecated in JDK 19 for [JDK-8281181](https://bugs.openjdk.org/browse/JDK-8281181), and [JDK-8281181](https://bugs.openjdk.org/browse/JDK-8281181) has been backported to jdk17u-dev and jdk11u-dev, so I think it will be useful to backport [JDK-8282684](https://bugs.openjdk.org/browse/JDK-8282684) to jdk17u-dev and jdk11u-dev.
