Looks like you renamed pageId to commentOwnerId in RemoteCommand.java which breaks compatibility for clients. I think all you needed to do was leave the field name the same and add the new accessor functions with the better terminology. Please revert this change for 4.1.1! Also, no where is there a mention in JIRA or elsewhere that this change took place!

Specifically:

1. If using a client based on < 4.1 wsdl against Confluence 4.1 you get

   org.xml.sax.SAXException: Invalid element in org.swift.common.soap.confluence.RemoteComment - commentOwnerId
   

2. If using a client based on 4.1 wsdl against a Confluence < 4.1 you get

   Remote error: org.xml.sax.SAXException: Invalid element in com.atlassian.confluence.rpc.soap.beans.RemoteComment - commentOwnerId
