Cast Exception

Özerk Dolanbay

Hi all,

After upgrading jira from 5.2.9 to 6.1.5, some groovy scripts does not work. In the log records, there is a cast exception as "Cannot cast object 'my user object' with class 'com.atlassian.jira.user.DelegatingApplicationUser' to class 'com.atlassian.crowd.embedded.api.User'

Is there any suggestions?

You can use the ApplicationUsers class to convert between User and ApplicationUser.

Thank you Henning, now it is clear. I get values from custom fields which contain users and use "User" object for return values. However, according to the document you shared above it says:

If you read values from CustomFields containing Users. In older versions CustomFieldsused to return User object, in 6.0 JIRA returns ApplicationUser. As in 6.0 these types are totally incompatible, you will probably get an exception:

java.lang.ClassCastException: com.atlassian.jira.user.DelegatingApplicationUser cannot be cast to com.atlassian.crowd.embedded.api.User

So, I add "import com.atlassian.jira.user.ApplicationUsers" line in script code and use <strong><a href="https://docs.atlassian.com/jira/latest/com/atlassian/jira/user/ApplicationUsers.html#toDirectoryUser(com.atlassian.jira.user.ApplicationUser)" rel="nofollow noopener noreferrer">toDirectoryUser</a></strong>(<a href="https://docs.atlassian.com/jira/latest/com/atlassian/jira/user/ApplicationUser.html" title="interface in com.atlassian.jira.user" rel="nofollow noopener noreferrer">ApplicationUser</a> user) method to convert ApplicationUser to User.

Am I right?

Yes, if the following method needs an ApplicationUser.
