E. Sammer commented on MRUNIT-9:
--------------------------------
Not sure how this one worked before. The iterator() method on
InspectableIterable always invokes its baseIter's iterator() method and creates
a new instance of InspectableIterator. If the for (x : i) construct invokes
iterator() on i, you're always going to get a reset iterator and the failure
I'm seeing[1].
[1] My description of the error is wrong. The actual failure is actually that
the iterator doesn't reset and this code:
for (int v : i) {
count += v;
}
for (int v : i) {
count += v;
}
yields count == 8 if i contains 4 1s rather than 4.
