jigsaw/jake has just been sync'ed up so it now has jshell. Unfortunately it requires changes to work with modules, here's an example:

-> System.out.println("hi")
Exception in thread "main" java.lang.reflect.InaccessibleObjectException: Unable to make member of class REPL.$REPL9 accessible: module jdk.jshell does not read <unnamed module @51565ec2>

at jdk.internal.jshell.remote.RemoteAgent.main(jdk.jshell@9.0/RemoteAgent.java:56)

The main issue is that jshell is a named module that needs to access types in unnamed modules.

An additional issue is that jshell launches the debuggee with -Xbootclasspath, that option has been removed.

In addition, we need to look at the tests. All jshell tests are currently failing in jake, probably because they are missing @modules.
