A simple example. At first, I have the following consistent
class hierarchy:

public class C {
  int i;
  public C(int i) {
    this.i = i;
  }
}

public class C1 extends C {
  public C1(int i) {
    super(i);
  }
}

public class C2 extends C1 {
  public C2(int i) {
    super(i);
  }
  public static void main(String args[]) {
    C2 c = new C2(1);
    System.out.println("OK");
  }
}


Then by mistake I modify class C, so that it becomes incompatible
with C1:

public class C {
  int i,j;
  public C(int i, int j) {
    this.i = i;
    this.j = j;
  }
}

And invoke javac on C2.java. The output is below:

lombok{misha}: javac -verbose C2.java
[parsed C2.java in 6473 ms]
[loaded ./C1.class in 45 ms]
[parsed ./C.java in 5 ms]
[loaded /local/java/jdk1.2/jre/lib/rt.jar(java/lang/Object.class) in 6 ms]

[wrote C2.class]
[checking class C]
[wrote ./C.class]
[done in 13114 ms]

The compiler checks and recompiles class C, but does not recompile
class C1, though it depends on C and is now older than C! As a
result there is runtime problem:

lombok{misha}: java C2
Exception in thread "main" java.lang.NoSuchMethodError: C: method <init>(I)V not found
        at C2.main(Compiled Code)

Compiling C2.java with "-Xdepend" option does not eliminate this
problem.

Environment: CLASSPATH unset.
lombok{misha}: java -fullversion
java full version "JDK-1.2-V"

As far as I know, there is no spec on what the javac compiler is
supposed to do in such situation. But I believe that it is
natural to handle it.

The exception goes away if I don't use the -Xdepend option.

Unfortunately, the project has lots of propeitary source code
that I can't supply to you to reproduce the exception.

More and more often when I compile most of my sourcefiles
(under h:/src in the example)
I also import compiled classes (under u:/ in the example too, which i don't have/want to recompile)
The compiler crashes. I don't have a clue what happens:
but here's the commandline for you:
cd h:/src/se/posten/logistik/applications/xplod/gui/
