JIRA listener script to add assignee into Summary field

A little script to help the life better. This script is a Listener which update the summary of JIRA issue to add assignee info. I'm using JIRA Agile and its board doesn't show the assignee name so I create this script to display it in the summary field.

Code as following, save it with .groovy extension and then put it into atlassian-jira/WEB-INF/classes/com/xxx/listeners and then configure JIRA to use com.xxx.listeners.UpdateAssigneeSummaryListener as class

import com.atlassian.jira.event.issue.AbstractIssueEventListener;
import com.atlassian.jira.event.issue.IssueEvent;
import org.apache.log4j.Category;
import com.atlassian.jira.event.type.EventType;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.user.util.UserManager;
import com.atlassian.jira.event.type.EventDispatchOption;
import com.atlassian.jira.component.ComponentAccessor;

class UpdateAssigneeSummaryListener extends AbstractIssueEventListener {
    Category log = Category.getInstance(UpdateAssigneeSummaryListener.class)

    @Override
    void workflowEvent(IssueEvent event) {
        Issue issue = event.getIssue();
        Long eventTypeId = event.getEventTypeId();
        if ((eventTypeId.equals(EventType.ISSUE_ASSIGNED_ID) || eventTypeId.equals(EventType.ISSUE_CREATED_ID)) && issue.getResolutionDate() == null)
        {
            def test = (issue.getSummary() =~ /^\[([A-Za-z]+)\]/)
            def summary
            def assignee = issue.getAssigneeId()
            if (test.getCount() != 0)
            {
                // Replace the user in bracket.
                summary = (issue.getSummary() =~ /\[([A-Za-z]+)\]/).replaceFirst("[${assignee}]")
            }
            else
            {
                summary = "[${assignee}] ${issue.getSummary()}"
            }

            MutableIssue mutableIssue = (MutableIssue)issue;
            mutableIssue.setSummary(summary);
            IssueManager issueManager = ComponentAccessor.getIssueManager();
            UserManager userManager = ComponentAccessor.getUserManager();
            issueManager.updateIssue(event.getUser(), mutableIssue, EventDispatchOption.DO_NOT_DISPATCH, false)
        }
    }
}

Should we move to KVM?

The virtualization wars between VMWare and KVM is not over. KVM is recently adapted by many companies such as IBM,.

Should we migrate to KVM? It's free/low cost than VMWare but show better results than VMWare...Hmmm....
