[graalvm-users] GraalVM to extend a native framework

[Dmitry Timofeev]

Hi,

I’m working on making a framework in a native language (Rust) extensible 
in other languages (Java, Python). We currently use JNI, which is 
low-level and error-prone. I consider if GraalVM would make some things 
easier or make the integration more efficient. Would anyone please help 
with these questions?

1. Is it a good use-case for GraalVM? It seems so from the docs, as 
GraalVM aims to eliminate the costs associated with calling code running 
on a VM from the native code and vice-versa.
2. The reference documentation says C --> Java is not supported yet, but 
coming soon. Does it mean that developers will be able to use Java from 
C with /no/ JNI (= pass arbitrary structs, call any Java method from any 
native thread)? Is it going to be a viable full-featured replacement for 
any JNI use-case?
3. If I do such integration of a native language with Java the old way — 
using JNI, native methods and libraries — but run on GraalVM, will this 
application enjoy any inter-language optimizations?

Thanks!
