Description

A minimal extension of groovy.io.Console throws "groovy.lang.MissingPropertyException: No such property: scriptRunning" after successfully evaluating a script.

GWLSTConsole.groovy

package com.middlewareman.mbean.weblogic.shell

class GWLSTConsole extends groovy.ui.Console {

	GWLSTConsole() {
		super()
	}

	GWLSTConsole(Binding binding) {
		super(binding)
	}

	GWLSTConsole(ClassLoader parent, Binding binding) {
		super(parent, binding)
	}

	GWLSTConsole(ClassLoader parent) {
		super(parent)
	}
}

In general, it would be great if groovy.ui.Console would be more flexible for adapting to your own DSLs. In my case, for example, I would like to customise the title. It is currently hard-coded in two places, and extending the class would be one way of overriding these.
