groovysh or any other REPL

[Tobia]

Hello

How can I use GroovyServ to start a Groovy REPL, without incurring in the bad startup time (5s on a fast machine) of stock groovysh?

I've tried various combinations of

groovyclient -e 'org.codehaus.groovy.tools.shell.Main.main(args)'

but they all cause groovyserver to die.
