Changing the internal rules by which the runtime operates — and modules’ access are at the core of these rules — is the very definition of low-level instrumentation.

Unfortunately, I cannot consider your example appropriate for the situation under discussion. We are not talking about changing 5 to 6, but rather about granting or modifying access to a module’s packages. By other words, I don't need 5 to be 6, I just need jline to work with jansi? Do you see the difference?

If the only solution is to use agent and there is no other normal, standard, elegant solution I want to be sure of it.

Because, if this is the only solution then the following statement will be true - "If you have two layers and the most common library modules, to make it work YOU NEED TO USE AGENT AND JAVA INSTRUMENTATION".
Something like that.
