[Kaffe] yet another invocation bug found!

[Moses DeJong]

Hello all.

I seem to have found another problem with the invocation system.
It looks like package access is not getting checked on dynamic
method invocations. Here is a small example that shows the problem.


// File NonMember.java

import java.lang.reflect.*;
import testpkg.PkgMember;

public class NonMember {
    public static void main(String[] argv) throws Exception {
	PkgMember mem = new PkgMember();

	Method foo = PkgMember.class.getDeclaredMethod("foo", null);
	
	System.out.println("foo is " + foo);

	// This should raise an IllegalAccessException
	foo.invoke(mem,null);

	System.out.println("Error!");
    }
}



// File testpkg/PkgMember.java

package testpkg;

import java.util.*;

public class PkgMember {

    // This constructor is public

    public PkgMember() {}


    // This method has package access
    
    void foo() {}
}



JDK output

% java NonMember
foo is void testpkg.PkgMember.foo()
java.lang.IllegalAccessException: testpkg/PkgMember
        at NonMember.main(Compiled Code)



Kaffe output

% kaffe NonMember
foo is void testpkg.PkgMember.foo()
Error!



I hope that helps
