    I started noticing these errors after upgrading to macOS 13. However I suspect they started after I upgraded to Android Studio Electric Eel (2022.1).

    flutter doctor was reporting the following:

    I symlinked the jbr director to jre according to this answer. This resolved both complaints. No other action was required.
