The delegate is deprecated. Replace your service task containing this delegate with a script task, for example:

```
<scriptTask id="scripttask1" name="Notify Requester" scriptFormat="groovy" activiti:autoStoreVariables="false">
    <script><![CDATA[
        def usersIds = users.getUserIds("role(Requester)");
        if (usersIds.isEmpty()){
            loggerApi.warn("No users to send a mail to, no mail will be sent");
        } else {
             mail.sendMails(usersIds, "in-progress", null, execution);
        }
    ]]></script>
</scriptTask>
```
