Integrate Oracle GraalVM into Enso CI

[JaroslavTulach]

Oracle GraalVM (formerly GraalVM EE) is said to offer performance benefits as well as additional functionality (for example isolates as needed by #9171). Enso shall not ignore Oracle GraalVM, but continuously work towards using the best of both:

• GraalVM Community
• Oracle GraalVM

Oracle GraalVM comes with extremely benevolent license (for a non-open source component) which allows

use by any user including commercial and production use. Redistribution is permitted as long as it is not for a fee

As such there is nothing stopping us to use and test against Oracle GraalVM in our CI pipelines. Thus, let's start with using Oracle GraalVM in our CI. Having such a CI pipeline set up we can move towards more intricate usages of Oracle GraalVM as outlined by

• Speed Startup by 33% with the use of GraalVM Polyglot Isolates #9171

Tasks

Preview Give feedback

1. Set a CI pipeline up that builds and tests engine with Oracle GraalVM
2. Execute (engine) benchmarks against Oracle GraalVM

@JaroslavTulach
Is it enough to just replace the GraalVM package with the non-community one in PATH/JAVA_HOME/GRAALVM_HOME and then run everything "as usual" or is there something more that CI needs to do here? Do we need to somehow inform sbt/engine that it is provided a different Graal flavour?

Yes, that should be enough. When working on #9171, that's exactly what I have done. Download Oracle GraalVM start sbt with that JVM and then do everything normally. There appears a warning in the logs, but otherwise things seem to work fine.
