Build fails when disabling jvmti

[Sanne Grinovero]

Hello all,

I'm experimenting building Leyden locally with non-default configurations,
with the intent of comparing its potential as an alternative to GraalVM
native-images, and one of my goals would be to produce a minimal JVM build
which exclusively includes the components that our applications are going
to need at runtime.

This implies being very selective with the JVM features I choose at
configuration time; I've already opened some minor issues identified during
such experiments.

Today I noticed today that if I exclude the "jvmti" feature, the premain
branch of Leyden doesn't compile:

I'm wondering if I should open an issue for this case? I appreciate it's
early days and that such aspects might not be a priority currently!

Thanks,
