Github user edwardoliveira commented on a diff in the pull request: https://github.com/apache/zookeeper/pull/160#discussion_r98967876 --- Diff: src/java/main/org/apache/zookeeper/server/DataTree.java --- @@ -1045,18 +1046,16 @@ private void getCounts(String path, Counts counts) { if (node == null) { return; } - Set<String> children = null; + String[] children = null; int len = 0; synchronized (node) { - children = node.getChildren(); + Set<String> childs = node.getChildren(); + children = childs.toArray(new String[childs.size()]); --- End diff -- FYI (only): I *guess* some tests broke 'cause `toArray` copies the contents of `childs` to `children` while `node.getChildren()` returns a internal reference (subject to underneath change) to `children`. So, it would need to be something like `children = new HashSet<>(childs);`
