[modules-dev] re-export failed 'Imported module in error state'

[Benedikt Hauptmann]

Hi Everyone,

I tried to test the following scenario with source-release 09_apr_2008:

Super package 'module_API' contains a set of interfaces describing an
custom API.
Both 'module_impl1' and 'module_impl2' containing implementations of the
interfaces declared in 'module_API'.

	package module_impl1;
	import java.lang.reflect.Superpackage.*;
	import java.module.annotation.*;
	@Version("1.0")
	class super_package {
	    exports module_impl1$Factory, module_API$IConnection,
module_API$IResult;
	    uses java$se, module_API;
	}

As you can see, module_impl1 also re-exports module_API$IConnection and
module_API$IResult!!!!!!! (ref: JSR-277, 02.10.06, Page 16)

'myProject' is using 'module_impl1':

	package myProject;
	import java.lang.reflect.Superpackage.*;
	import java.module.annotation.*;
	@MainClass("myProject.Main")
	@Version("1.0")
	class super_package {
	    exports myProject$Main;
	    uses java$se, module_impl1;
	}


Compiling and packaging works fine.
But starting 'myProject' crashes with the following exception:

Is this a bug in openJDK, or is re-exporting not yet implemented?

Thanks,
