Hi Daniel,
First of all, the change looks good to me. The broken
if (destroyed) {
return n;
}
part looks like a "copy and paste" from some other method in the ThreadGroup
class. They use recursion a lot.
Might it be the case that not only the returned value is wrong, but also the
populated list is corrupted? After all the returned value is used as an index
for the next insertion.
