GTNPORTAL-3510 Possible memory leaks, consistency issues and concurrency issues in ScriptGraph
Ah, good that you mentioned it! I actually wanted to speak particularly about this. It is actually test code. I guess, it is not a good practice to mix test and production code, but if this was a test case, all fields of SriptGraph would have to have package access. In this way, the fields can stay private and only validate() has default access. Moreover, I can invoke validate after all modifications that are done in test cases (as I indeed do). I could comment the method in this sense, but can't you see a cleaner design for this?
