Review Comment:
i believe this could be changed to `if (file == null)` which is the criteria
for success?
On first glance this algorithm looks more complicated than it actually is, I
believe the main reason is because the index is passed to the second loop for
the lone purpose of reusing the variable.
but its in essence two independent for-each loops, both seem to be in
reverse.
we can't do java 21 just yet but soon we might be able to. So this could
probably be 2x reverse view iterations like
```java
for (String trace : Arrays.asList(st).reversed()) {
if (found) {
file = ...;
break;
}
}
```
or 2x by using java 8 streams
```java
Optional<File> result = Stream.of(st)
.sorted(Comparator.reverseOrder())
.filter(trace -> {
return true; // todo
})
.findFirst();
```
might work too
