[JENKINS-51501] Parameterized Trigger Plugin Dynamic downstream projects fails "array out of bounds"

I am using using Active choice plugin for fetching job list:

 

def choices=[:]

jenkins.model.Jenkins.instance?.getAllItems(com.cloudbees.hudson.plugins.folder.Folder).each { folder ->

 println "Folder - ${folder}"

 folder.getItems().each {

 println "${it.name}"

 choices.put(folder.name+'/'+it.name, it.name)

 } 

}

return choices

 

Result saved in variable JOBS, and then passed to Parameterized trigger plugin in post-build actions.

 

Post build action: Trigger parameterized build on othern projects.

Projects to build: ${JOBS}

 

Variable JOBS looks like

```
JOBS=DEV/Build,DEV/Test,DEV/Deploy
```

 

Exception raised then parameterized plugin iterates over variable:

java.lang.ArrayIndexOutOfBoundsException: 1

Problem is in cycle

In my scenario:

String[] projects = ["DEV/Build", "DEV/Test", "DEV/Deploy"]

 String[] vars = ["$JOBS]

Iterating over vars is not possible, but upstream jobs still executed.

Maybe something like: if ((vars.length == 1 ? vars[0] : vars[i]).trim().contains("$")) {
