The term "boot classpath" comes from Java's Bootstrap Classes, which are the classes that implement the Java Platform. By default, bootstrap classes are in the `rt.jar` and several other jar files in the `jre/lib` directory according to [How Classes are Found](https://docs.oracle.com/javase/8/docs/technotes/tools/findingclasses.html).
The Scala compiler has `-javabootclasspath <path>` flag to override Java boot classpath. I assume the intent is to allow overriding classes in Java standard library.
For the Java boot classpath, the `scala` script justs puts everything in `lib/` on it.
This is not the right thing to do because it makes classes not on the user's classpath available.
It also forces a particular version of the config, JLine, and JAnsi libraries.
