I applied it and could successfully build Core.java, but not
HttpHandlerServlet.java. The problem might be related to the following
test case (guess what I did last night). The value of id is horribly
munged:

[root@rm03-24-131-185-22 /freenet]# gcj -o test --main=Test Test.java
[root@rm03-24-131-185-22 /freenet]# ./test
Works here: 1234567890
But not here: 4627002352841261056

It will usually repeat the same value time after time, but once and a
while it gave me a different one. This test case seems to always give me
the above, but in its natural environment it occasionally was different.

public class Test
{
    public static void main(String[] args) {
        Test t = new Test();
    }

    public Test() {
        Inner1 i = new Inner1();
        i.doThing();
    }

    protected abstract class Inner
    {
        protected long id;

        public Inner() {
            id = 1234567890;
        }
    }

    protected class Inner1 extends Inner
    {
        public Inner1() {
            super();
        }

        public void doThing() {
            Inner2 i2 = new Inner2();
            System.out.println("Works here: "+id);
            i2.printVal();
        }

        private class Inner2
        {
            public void printVal() {
                System.out.println("But not here: "+id);
            }
        }
    }
}
