Create linked issue with new watcher is not working

[Marton Danoczy]

Dear Fidel,

thank you very much for this wonderful plugin, I use it to replace everything else we used to have (JMWE, JSU, ...).

I have encountered a problem when creating linked issues in a transition:

Create one issue. 
Issue type: Story 
Project: Current Project 

Summary: text in basic parsing mode 
%{Summary}

Description: text in basic parsing mode 
%{Problem Analysis}

Set fields:
Field         Type of Value                Value
Reporter      Parsed text (advanced mode)  last(usersWhoTransitioned("Analysis", "Under Review"))
Priority      Field in current issue       Priority
New watchers  Field in current issue       Reporter

Issue Links:
Issue Link Type   Linked Issues   Condition
created by        Current issue   

Post-function will only be executed if the following boolean expression is satisfied: %{Resolution} ~ "Create Story"

This feature will be run as user in field Current user. by JWT

Executing this post function results in the error message:

Error occurred while creating issue. This could be due to a plugin being incompatible with this version of JIRA. For more details please consult the logs, and see: http://confluence.atlassian.com/x/3McB com.atlassian.jira.user.DelegatingApplicationUser cannot be cast to java.util.Collection

When I remove creating the new watchers, the post-function succeeds.

Hi @martond,

Thank you for kind words.

Can you, please, confirm the version of JWT and JIRA you are using?

Is it possible that you send your server's log file to [e-mail]?

[Marton Danoczy]

Sure. JIRA Software 7.5.0 and JWT 2.2.42.

Here's the stack trace from the log:

I have redacted the last three bytes of the IP, I hope you don't mind.

PS: I assumed you need only this stack trace from the logs. If you need more, please feel free to ask.
