Marius Petria created SLING-5578:
------------------------------------
Summary: Json rendering is using recursion for processing flat
trees and causes stack overflows
Key: SLING-5578
URL: https://issues.apache.org/jira/browse/SLING-5578
Project: Sling
Issue Type: Bug
Components: Commons
Reporter: Marius Petria
{{ResourceTraversor.collectChildren}} is unnecessarily using recursion and
causes stack overflows for flat trees.
Example: for a node with 10k direct children it adds 10k calls on the stack.
This should be implemented in an iterative way or at most it should do
recursion only for the tree depth.
