[GitHub] [jmeter] vlsi opened a new issue, #5925: CSVDataSet relies on System.identityHashCode uniqueness for ThreadGroup and Thread

["vlsi (via GitHub)" <gi...@apache.org>]

vlsi opened a new issue, #5925:
URL: https://github.com/apache/jmeter/issues/5925

   ### Expected behavior
   
   `CSVDataSet` should not rely on `System.identityHashCode` uniqueness as it is never guaranteed.
   
   I think `CSVDataSet` should leverage smart cloning like in https://github.com/apache/jmeter/pull/5916, so it would not require accessing `System.identityHashCode(threadGroup)` every time.
   As a bonus, the alias computation could be done just once, not for every execution.
   
   See https://github.com/apache/jmeter/pull/693
   
   ### Actual behavior
   
   _No response_
   
   ### Steps to reproduce the problem
   
   Add a test that configures `CSVDataSet` with `SHARE_GROUP` or `SHARE_THREAD`. Use `-XX:hashCode=2` to trigger OpenJDK Hotspot to produce duplicate values for `System.identityHashCode`.
