Or GroovyShell could set parent as 
Thread.currentThread().getContextClassLoader() instead of null in its 
constructors.  This is what Groovysh does:


    Groovysh(final ClassLoader classLoader, final Binding binding, final IO io) 
{

        this(classLoader, binding, io, createDefaultRegistrar(classLoader))

    }


    Groovysh(final Binding binding, final IO io) {

        this(Thread.currentThread().contextClassLoader, binding, io)

    }


    Groovysh(final IO io) {

        this(new Binding(), io)

    }


    Groovysh() {

        this(new IO())

    }

 passed the current class loader to the new GroovyShell as the parent loader, 
continuity could be maintained.  Can anyone see a problem with this?

FYI, GroovyStarter creates a RootLoader that is configured by its "--classpath" 
arguments.  Then runs its "--main" class argument.  When groovy.ui.GroovyMain 
is that main class, it resets the thread's context class loader from the 
RootLoader to a new loader provided by "new GroovyShell(new 
CompilerConfiguration(command line processing)).getClassLoader()".

Subject: groovy.ui.GroovyMain and groovy.ui.Console classpath arguments


Both GroovyMain and Console claim to accept "--classpath" arguments, however 
neither class has any processing for them.  How are these arguments supported?  
Is GroovyMain or Console supposed to be able to be run programatically?


What I am trying to do is use GroovyStarter to bootstrap a basic Java/Groovy 
environment that groovy.ui.GroovyMain (for scripts) or groovy.ui.Console (for 
interaction) can be run from.  What I am finding is that the classpath given to 
GroovyStarter is not propagating to GroovyMain.  So I try and move the 
"--classpath" arguments from GroovyStarter to GroovyMain and the latter just 
ignores them.  I'd actually prefer if GroovyStarter properly transferred its 
classpath to its "--main" class.
