ArrayUtil indexOf/contains not working

[Rachel55]

Hello.  I am trying to create a script for a login rule.  I am testing in backgroud scripts.  The script is supposed to look for a specific role for the logged in user.  Without the if statement, the array will print, and I can see that it contains itil. When the if statement is added, it gives the error message "Javascript compiler exception: Java class "[Ljava.lang.String;" has no public instance field or method named "size". (sys_script_include.fb32a2d8c0a80a6000e907036f484b5b.script; line 61) in:".  I get the same error whether I am using "contains" or "indexOf".

var arrUtil = new ArrayUtil();

var u = gs.getUser();

var myArray = u.getRoles().toString().split(",");

if (arrUtil.contains(myArray, "itil")){

gs.print("yes");

}

for (i=0; i<myArray.length;i++) {

gs.print(myArray[i]);

}

Now this If statement is not working.  It works if you split it into two separate if statements, but not with the &&.

var myArray = gs.getUser().getRoles().toString().split(",");

if(gs.getUser().hasRole('itil')) && (myArray.length>0){
gs.info('yes');
}

try this 

var myArray = gs.getUser().getRoles().toString().split(",");

if(gs.getUser().hasRole('itil') && myArray.length>0){
gs.info('yes');
}

Now it prints yes no matter what I put in the hasRole parentheses.

because admin have all the role

I put nonsense in the parentheses and it still prints yes.
