/* Note [Classpath Separation]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~
 * Projects using the language runtime do not depend on it directly, but instead
 * the language runtime is put on the Truffle classpath, rather than the
 * standard classpath. This is the recommended way of handling this and we
 * strive to use such structure everywhere.
 * See
 * https://www.graalvm.org/docs/graalvm-as-a-platform/implement-language#graalvm
 *
 * Currently the only exception to this are the tests of the runtime project
 * which have classpath separation disabled, because they need direct access to
 * the runtime's instruments.
 *
 * To ensure correct handling of dependencies by sbt, the classpath appended to
 * Java options, should be based on `(runtime / Compile / fullClasspath).value`
 * wherever possible. Using a key from the runtime project enables sbt to see
 * the dependency.
 *
 * Assembly tasks that build JAR files which need `runtime.jar` to run should
 * also add a dependency on `runtime / assembly`.

/* Note [Unmanaged Classpath]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~
 * As the definition of the core primitives in `core_definition` is achieved
 * entirely using the graph macros, this means that the IDE experience for those
 * using these primitives is very poor.
 *
 * To get around this, we want to treat the core definition as a .jar dependency
 * to force the IDE to depend on bytecode for its diagnostics, rather than the
 * source code (as this means it sees the macros expanded). A standard workflow
 * with local publishing would not recompile the definition automatically on
 * changes, so the `unmanagedClasspath` route allows us to get automatic
 * recompilation but still convince the IDE that it is a .jar dependency.

/* Note [HTTPS in the Launcher]
 * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 * The launcher uses Apache HttpClient for making web requests. It does not use
 * Java's stdlib implementation, because there is a bug (not fixed in JDK 11)
 * (https://bugs.openjdk.java.net/browse/JDK-8231449) in its HTTPS handling that
 * causes long running requests to freeze forever. However, Apache HttpClient
 * still needs the stdlib's SSL implementation and it is not included in the
 * Native Images by default (because of its size). The
 * `--enable-all-security-services` flag is used to ensure it is available in
 * the built executable.
