Description
Reference: https://mail.openjdk.org/pipermail/jigsaw-dev/2023-March/014816.html
The intention is to disable allowing dynamic attach of agents by default starting with Java 21. The runtime attach component should at a minimum enhance the README to mention the newly required JVM commandline arg. It would also be great to have a test/example to cover this use and demonstrate that it [still] works after 21.
