Question

I am not able to iterate through that global(accessible by all threadgroups) arraylist.

JMeter's ForEach Controller can only iterate JMeter Variables, not properties so the options are in:

1. Either use Loop Controller with the number of loops equal to the number of items in the arraylist

2. Or convert the arraylist into JMeter Variables using a suitable JSR223 Test Element and Groovy code like this:

   def list = props.get('list')
   
   1.upto(list.size(), { index ->
       vars.put('var_' + index, list[index - 1])
   })
   

   it will generate the following JMeter Varibles

   var_1=first item of your list
   var_2=second item of your list
   etc
   

   and these variables could be used in the ForEach Controller normally
