It looks like another API is needed so the component can figure out if the actual element has been cloned or not. For instance, in case like https://github.com/apache/jmeter/pull/727, `HeaderManager#assertMutable()` should be able to tell if the specific `HeaderManager` is cloned or not. If a code creates a temporary `HeaderManager` object for the purpose of merging the headers, then the temporary `HeaderManager` should not fail with something like "oh, this is a shared instance, stop modifying it". It sounds like `NoThreadClone#freeze()` method which would signal the component the instance is reused. Then `TreeCloner` would call `freeze` on non-cloned objects. --- Unfortunately, it reminds me of the new memory management in Kotlin Native : https://kotlinlang.org/docs/native-migration-guide.html Initially, they had a memory model which the user must call `freeze` object before sharing the object cross-threads. That memory model has proven to be hard to use, and they went with a garbage collector. Even though our goals are slightly different, it sounds related. -- This is an automated message from the Apache Git Service.
