To allow Java to control the computer (eg mouse cursor position, keyboard etc) - click the Apple icon --> System Preferences --> Security & Privacy --> Privacy --> Accessibility --> tick to enable java to control the computer.

If you are using OpenJDK from Amazon Corretto (recommended over Java JDK from Oracle), need to enable this as well for Terminal app, see post below this one for screenshot and details.

(Amazon Corretto's distribution of OpenJDK is recommended over Java JDK as Oracle has made Java JDK free only for private non-commercial usage, while Amazon Corretto is free, has no usage restrictions and is also available for Windows, macOS, Linux. Details at aisingapore/TagUI#589).
