Licensing question

[Raffaello Giulietti]

Hi all,

I'm aware that this might not be the ideal place to ask about licensing
issues but I'm just looking for unbinding opinions, not legal advice.

My understanding is that Graal is licensed under the "viral" GPL while
Truffle is licensed under the less restrictive GPL with Classpath exception.

What does this imply for a Truffle language implementation that makes
use of Graal for performance, even if it does not link directly to the
Graal API?
Does it indirectly inherit the stricter GPL status or can it be
distributed with any license as allowed by the GPL with Classpath exception?

Greetings
Raffaello
