Casting error from DelegatingApplicationUser to api.User in post function script (Groovy)

I have a script that takes a member group and splits the current users into an email string that gets used by a custom email function. The error I am getting says 

2017-06-20 15:28:36,113 ERROR [workflow.ScriptWorkflowFunction]: Special Test Priority Value option: 5 - Stop working on everything else and get this done
2017-06-20 15:28:36,113 ERROR [workflow.ScriptWorkflowFunction]: The reporter is: Hank Hepler

2017-06-20 15:28:36,160 ERROR [workflow.ScriptWorkflowFunction]: *************************************************************************************
2017-06-20 15:28:36,160 ERROR [workflow.ScriptWorkflowFunction]: Script function failed on issue: null, actionId: 1, file: <inline script>
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'a092rzz(a092rzz)' with class 'com.atlassian.jira.user.DelegatingApplicationUser' to class 'com.atlassian.crowd.embedded.api.User'
	at Script104.getGroupEmails(Script104.groovy:83)

I fixed the null issue error, but am kind of lost on the casting of the object. How can I get the users in the correct object (User)? Below is the function... we just upgraded to 7 so I have this in multiple places.

def getGroupEmails(String groupName)
	def gusers = new StringBuilder();
	def userManager = ComponentAccessor.getUserManager();
	def groupManager = ComponentAccessor.getGroupManager();
	def group = userManager.getGroup(groupName);
	List<User> usersInGroup = (List)groupManager.getDirectUsersInGroup(group)

	for (User user : usersInGroup){
		if (gusers.length() > 0) gusers.append( ", " );
		gusers.append( user.getEmailAddress() );    
	return gusers.toString();

Any help will be greatly appreciated!
