I am evaluating activiti and transactional subprocess is one of the key feature that I am looking at. The user guide has marked it as [EXPERIMENTAL]. So, I am not sure if this feature is stable and can be used in production.
Can some one confirm if this feature is Stable or not. If not, then by what time we can expect it to be.
It is usable and stable, however it is marked as experimental as we want some more unit tests for it. Check the unit tests to see which cases we have all tested currently and see if it matches what you need.
