Help with Groovy scripted field

Hi,

This is a weird one. I am trying to make a scripted field that tracks the last commenter of an issue. I actually have something that works pretty well.

However, I want to modify it to be able to omit a user (weird use case, I know).

Example: let's say there are 4 comments on an issue, from user A, and user B. I want to look at all comments in an issue, but *only* report the last comment from user A.

This is what I have so far(see below). It doesn't seem to work. Any tips appreciated!

import com.atlassian.jira.component.ComponentAccessor

def commentManager = ComponentAccessor.getCommentManager()
def comments = commentManager.getComments(issue)

if (comments) {
    comments.each {
        if (it.authorUser.toString().contains ('userB')) {

            comments.remove(it)

        }

    }

}

comments.last().authorUser

Not exactly sure what I doing wrong here. I am new to groovy, so perhaps I am doing some silly syntactical mistake? I get errors like so in the logs:

javax.script.ScriptException: java.util.ConcurrentModificationException

 A stacktrace has been logged.

Okay,

I got it to work (at least so far, by doing this):

import com.atlassian.jira.component.ComponentAccessor

def commentManager = ComponentAccessor.getCommentManager()
def comments = commentManager.getComments(issue)

comments.removeAll { it.authorUser.toString().contains ('userB') }
comments.last().authorUser

If there are any better approaches, let me know!

Something like:

import com.atlassian.jira.component.ComponentAccessor

def commentManager = ComponentAccessor.getCommentManager()
commentManager.getComments(issue)*.author.reverse().findResult {it.author != "baduser"}

.reverse() might not be necessary... not sure what order they are returned in by default.
