Pavel Marek 5a7ad6bfe4 Upgrade enso to GraalVM for jdk 21 (#7991) ... Upgrade to GraalVM JDK 21. ``` > java -version openjdk version "21" 2023-09-19 OpenJDK Runtime Environment GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15) OpenJDK 64-Bit Server VM GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15, mixed mode, sharing) ``` With SDKMan, download with `sdk install java 21-graalce`. # Important Notes - After this PR, one can theoretically run enso with any JRE with version at least 21. - Removed `sbt bootstrap` hack and all the other build time related hacks related to the handling of GraalVM distribution. - `project-manager` remains backward compatible - it can open older engines with runtimes. New engines now do no longer require a separate runtime to be downloaded. - sbt does not support compilation of `module-info.java` files in mixed projects - https://github.com/sbt/sbt/issues/3368 - Which means that we can have `module-info.java` files only for Java-only projects. - Anyway, we need just a single `module-info.class` in the resulting `runtime.jar` fat jar. - `runtime.jar` is assembled in `runtime-with-instruments` with a custom merge strategy (`sbt-assembly` plugin). Caching is disabled for custom merge strategies, which means that re-assembly of `runtime.jar` will be more frequent. - Engine distribution contains multiple JAR archives (modules) in `component` directory, along with `runner/runner.jar` that is hidden inside a nested directory. - The new entry point to the engine runner is [EngineRunnerBootLoader](https://github.com/enso-org/enso/pull/7991/files#diff-9ab172d0566c18456472aeb95c4345f47e2db3965e77e29c11694d3a9333a2aa) that contains a custom ClassLoader - to make sure that everything that does not have to be loaded from a module is loaded from `runner.jar`, which is not a module. - The new command line for launching the engine runner is in [distribution/bin/enso](https://github.com/enso-org/enso/pull/7991/files#diff-0b66983403b2c329febc7381cd23d45871d4d555ce98dd040d4d1e879c8f3725) - [Newest version of Frgaal](https://repo1.maven.org/maven2/org/frgaal/compiler/20.0.1/) (20.0.1) does not recognize `--source 21` option, only `--source 20`.		2023-11-17 18:02:36 +00:00
