[I] Listeners receive null as a property value inside a groovy script when run from CLI [jmeter]

[via GitHub]

artemkurov opened a new issue, #6323:
URL: https://github.com/apache/jmeter/issues/6323

   ### Expected behavior
   
   `${__groovy(props.get("baseDir")+"/results/latency_data.csv")}` evaluated to 
correct file path like 
`/Users/username/projects/qa-perf/performance/jmeter/results/latency_data.csv`
   
   ### Actual behavior
   
   `${__groovy(props.get("baseDir")+"/results/latency_data.csv")}` evaluates to 
`null/results/latency_data.csv`

   ### Steps to reproduce the problem
   
   ### Prerequisites:
   Having a test plan (attached here 
[bug.jmx.zip](https://github.com/user-attachments/files/16459604/bug.jmx.zip)), 
containing:
   - setUp thread group, which contains 
   --- init JSR223 Sampler
   - main thread group with 
   --- Dummy sampler
   --- Simple Data Writer (or any listener)
   - tear down thread group with
   --- JSR223 Sampler
   
   init JSR223 Sampler having this code:
   ```
   import org.apache.jmeter.util.JMeterUtils;
   import org.apache.jmeter.services.FileServer
   
   // Do not show this sampler in report
   SampleResult.setIgnore()
   
   // Set base directory. Mainly needed for local run
   String baseDir = FileServer.getFileServer().getBaseDir()
   JMeterUtils.setProperty("baseDir", baseDir)
   log.info("Base directory set to " + props.get('baseDir'))
   ```
   
   Simple Data Writer having this as a filename:
   `${__groovy(props.get("baseDir")+"/results/latency_data.csv")}`
   
   Tear down JSR223 Sampler having this code:
   ```
   // Do not show this sampler in report
   SampleResult.setIgnore()
   
   String filePath = props.get('baseDir') + '/results/latency_data.csv'
   log.info('filepath=' + filePath)
   File file = new File(filePath);
   if(!file.exists()) {
        log.error('FILE NOT FOUND')
   }
   
   // Pasre file
   //...
   ```
   
   ### Reproducing
   1. Run test plan from GUI.
   2. Observe 
`/Users/username/projects/qa-perf/performance/jmeter/results/latency_data.csv` 
file is created and no errors in the log
   3. Launch terminal in baseDir folder (for me is 
`/Users/username/projects/qa-perf/performance/jmeter`)
   4. Launch the same test plan via CLI using command
   `jmeter -LINFO -n -j Buggy_Test_Plan.log -t bug.jmx -l Buggy_Test_Plan.jtl`
   5. Observe unexpected behavior:
   - File 
`/Users/username/projects/qa-perf/performance/jmeter/null/results/latency_data.csv`
 is created
   - ERROR in logs because JSR223 sampler could not find the file.
   - `INFO o.a.j.r.ResultCollector: Folder at 
/Users/username/projects/qa-perf/performance/jmeter/null/results was created`
   
   I assume that folder `null` is created because this happens before set of 
the variable `baseDir`, thus `props.get("baseDir")` returns null.
   But this flow does work through GUI mode, so should be a bug.
