[graalvm-users] java as a guest language?

[Erick Johnson]

Hello,

After passively following GraalVM work for some time, I'm starting to
get more hands on with it. Currently I'm interested in understanding
more about the instrumentation APIs
(https://urldefense.proofpoint.com/v2/url?u=https-3A__www.graalvm.org_docs_graalvm-2Das-2Da-2Dplatform_implement-2Dinstrument_-23simple-2Dinstrumentation-2Dagent&d=DwIBaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=9zUJig7JQXQ5iU1nBfmSzCoMYLSjrPBi21zwO6jOQ-U&s=I848zbKOnibdjNQhsHmKQIUEp8xPCEafnhiYkSVPB3w&e= ).

Particularly - is it possible to treat Java as a guest language in
order to use the truffle instrumentation and source APIs to inspect
Java code?

AFAICT this is not possible  - but  the first example from the
org.graalvm.polyglot.Source documentation - "From a file on disk" (
https://docs.oracle.com/en/graalvm/enterprise/19/sdk/org/graalvm/polyglot/Source.html)
- made me question whether or not I missed something.

Thanks

Erick
