UCCX script is failing with java exception

[kmurali.krishna]

we recently graded UCCX from 8* to 11.5

one of the custom java class if failing with "java.lang.Exception".

I am storing the call events in a java.util.arraylist variable and trying to pass the variable value while calling the custom class.

Java.util string at new environment:  §java.util.ArrayList§[CallStart||2018-05-29 15:31:11.424, OpeningMenuAttempt||2018-05-29 15:31:11.744, Hangup||2018-05-29 15:34:56.586, CallEnd||2018-05-29 15:34:57.624]§

Java.util string at old environment:  �java.util.ArrayList�[CallStart||2018-05-29 15:33:48.659, OpeningMenuAttempt||2018-05-29 15:33:49.031, Hangup||2018-05-29 15:34:40.715, CallEnd||2018-05-29 15:34:43.195]�

is this something to do with symbols at variable value. if so how we control the symbols.

please help to resolve.

thanks,

Murali.

Do you mind posting the script so can take a look?
Also when you validate the script do you get any errors or does it validate properly?
