Script runner does not work with scripted field properly after upgrade to JIRA 6.3

[e]

Hello,

I am using a Scripted Field to count the number of times an issue has been reopened.

Name: Reopen Counter
Type: Scripted Field
Issue type(s): Global (all issues)

But after I upgraded from JIRA 6.2 to 6.3 - the value "Reopen Counter" is 0 for all issues. Neither does it increment the values for new issues. I have the latest version of the Script Runner plugin. 

The way "Reopen Counter" is scripted:

import com.atlassian.jira.ComponentManager
import groovy.sql.Sql
import java.sql.Connection
import org.ofbiz.core.entity.ConnectionFactory
import org.ofbiz.core.entity.DelegatorInterface
ComponentManager componentManager = ComponentManager.getInstance()
delegator = (DelegatorInterface) componentManager.getComponentInstanceOfType(DelegatorInterface.class)
String helperName = delegator.getGroupHelperName("default");
this.issueid = issue.id
def sqlStmt = """
	SELECT NEWSTRING AS Status, count(*) AS Number
	FROM changeitem, changegroup, jiraissue
	WHERE changeitem.field = 'Status'
		AND changeitem.groupid = changegroup.id
		AND changegroup.issueid = jiraissue.id
		AND jiraissue.ID = ${this.issueid}
		AND changeitem.NEWSTRING = 'Reopened' 
	Group By NEWSTRING
"""
Connection conn = ConnectionFactory.getConnection(helperName);
Sql sql = new Sql(conn)
row = sql.firstRow(sqlStmt)
sql.close()
if (row == null)
{ v = 0 }
else 
{ v = row.Number }
d = (double)v
this.value = d

I hope that Jamie Echlin is going to help.

JIRA reindex - helped.
