NoClassDefFoundError encountered in custom JQL function

[Witold_Zabdyr]

I need to write a custom JQL function.
In the workflow is the stage "Waiting for approval". Each approver can individually accept/decline the issue. Some approvers are belonging to the defined group. The purpose of this function is to hide those issues in which someone from this group has already accepted/declined.
I made sure that the function body is working properly. I tested it in the script console and everything was OK. However, when I insert the function into the Adaptavist template, I get the error java.lang.NoClassDefFoundError: com / atlassian / servicedesk / api / approval / ApprovalService. Error is generated by the last line.

Any help will be really appreciated.
