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);
 }
 }
 }
}
