Claus Ibsen resolved CAMEL-9197.
--------------------------------
Resolution: Fixed
Assignee: Claus Ibsen
Fix Version/s: 2.17.0
We have improved the data format marshal to better support stream caching. It
may be improved in the latest 2.16.2 release. I tested with master.
On a JVM with 64mb limit I can find run this example and not eat up any memory.
In older versions the GC would also reclaim the memory but it could use
200-300mb during processing one of those files.
> Memory leak with .marshal().json() if stream caching enabled
