-----------------------------------------------------------------
I am going down the Rabbit Hole of the Scala REPL.
I think this is the right code branch
[https://github.com/scala/scala/blob/0c335456f295459efa22d91a7b7d49bb9b5f3c15/src/repl/scala/tools/nsc/interpreter/IMain.scala]
lines 357 to 352 define TranslatingClassLoader
It appears to be the central mechanism of the scala REPL to parse, compile and
load any class that is defined in the REPL. There is an open bug on the scala
issues section marking this class as having been identified as not thread-safe.

The scala stuff has a different idiom to Java so maybe the closing of
classloaders is less refined in experience (meaning it is just less clear what
is the right way to catch 'em all)

override def close(): Unit = {

}
perhaps .close() is not closing everything.
