Hi,
The code is supposed to be setting the cause of the exception so that
you can back-chain through the various levels to find it. For example,
with the program below:
import x10.io.Console;
public class StaticInitException {
static x:Int = f();
static def f() {
if (Math.sin(42) < 1000) { // should always happen
throw new Exception("I will try to break things.");
}
return 42;
}
static y:Int = x;
public static def main (args : Array[String]) {
Console.OUT.println("Value is: "+y);
}
}
You get a long & ugly stack series of stack traces (appended), but
all of the information is still there. Is the cause not being set
correctly in your example? If so, I'd be interested in trying to debug it,
since I thought I had things properly setup so it would do that.
thanks,
