Description

When ChildAxisQuery#advance is invoked, then the following while loop:

while (nextDoc > -1 && !indexIsValid(nextDoc)) {
nextDoc();
}

easily results in stacktrace below. This is because nextDoc returns NO_MORE_DOCS (Integer.MAX_VALUE) in case there are no hits any more, which results in IllegalArgumentException in indexIsValid

java.lang.IllegalArgumentException: docID must be >= 0 and < maxDoc=3
