Providing the following flags to enable JVMCI:

-XX:+UnlockExperimentalVMOptions
-XX:+EnableJVMCI

Causes the following warning:

[engine] WARNING: The polyglot engine uses a fallback runtime that does not support runtime compilation to native code.
Execution without runtime compilation will negatively impact the guest application performance.
The following cause was found: Truffle was loaded from the class-path. Use Truffle from the module-path instead. Did you disable polyglot class-path isolation?
