Speaking about kjc - is the project still alive?
I mean at the moment it looks like more and more
people start using kaffe and we're thus running
into several bugs in kjc that can be triggered by
pretty usual java programs (could've been spotted

As for the runtime checking stuff: there seems to
be another bug related to inner classes:

hkraemer at moose:/tmp/access-test$ cat a/test.java 
package a;
public class test
	protected static class inner
		public inner (){}
hkraemer at moose:/tmp/access-test$ cat b/test1.java 
package b;
import a.test;
public class test1 extends test
	public void bar ()
		new inner ();

	public static void main (String[] args)
		new test1().bar();

Looks like access to members of inherited inner
classes is denied (test case was compiled with
jikes 1.18).
