[GitHub] [jmeter] mwasplund opened a new issue, #5759: OpenModelThreadGroupController cannot be cast to LoopController
mwasplund opened a new issue, #5759:
URL: https://github.com/apache/jmeter/issues/5759
### Expected behavior
Using new Open Model Thread Group throws exception when there are lot of threads to hit the target RPS value.
### Actual behavior
```

```
### Steps to reproduce the problem
Note: Repro is on our internal service that cannot be shared here. Hopefully this is enough info.
* Create new test plan with Open Model Thread Group.
* Set target RPS to a value that will create heavy load
* As the threads increase over time it works fine until it hits a peak concurrent load that starts to throw the above exception.
