It uses an ArrayList to store its columns, foreign keys and indicies but treats the contents as a Set within the equals, hashCode and sortForeignKeys. On one particular project I've observed up to 2 minutes of the overall load time being consumed in these methods. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
