Some throws are expected and allowed (e.g Runtime SDE) and we need to make sure the markPools are cleaned up appropriately in this case so successive parses don't fail. The other ones like stacks are less important since the PState is thrown away, but mark pool persist between parses and leaks cause real issues. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
