Create Sub-Tasks for each User in Multi-User Picker (JIRA 6.1.5)

I'm wracking my brain with this... I'm trying to build a script runner post function to kick off multiple subtasks based on the users in a multi-user picker.
I've found a few pieces of code to work with, but I think one is stale in that it doesn't work with JIRA 6+ and the other you provided is for groups (tried to convert it to use a collection from the multi-user picker, but alas... it's that multi-user picker field that's getting me).
Here are links to the scripts I'm referring to:
I realize in the first, there needs to be some tweaking because of some changes that occurred with the object returned from the user picker custom field...
Something like so:
Collection<User> users = (Collection) ApplicationUsers.toDirectoryUsers(issue.getCustomFieldValue(cfApprovers))

Any help is appreciated.
I'm getting all sorts of errors from the can't cast error caused by the changes indicated above to:

Hi Trevor,

I think that your issue is due to a wrong usage of JiraAuthenticationContext method. You are using componentManager.getJiraAuthenticationContext().getUser() that return an ApplicationUser. createIssue, instead, need a User.

Try to use the following code :

...
subTask = componentManager.getIssueManager().createIssue(componentManager.getJiraAuthenticationContext().getLoggedInUser() , issueObject)
...

This should fix your issue.

Regards,

Fabio
