    [ https://issues.apache.org/jira/browse/SLING-1524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12869169#action_12869169 ] 

Justin Edelson commented on SLING-1524:
---------------------------------------

This is done in r946214.

There is one interesting problem related to the internal caches in the RPC serialization mechanism. It's described here: http://code.google.com/p/google-web-toolkit/issues/detail?id=4394

If you run into serialization problems with GWT and Sling, you should ensure that
1) You're doing an import (dynamic in the sample) of com.google.gwt.user.client.rpc.core.*
2) You are only serializing one version of a class

If one or both of these weren't true, make them true and the stop and start the Sling GWT Servlet bundle. If and when GWT implements a serlialization cache clear function, we can tie that in with a bundle listener. However, that would only solve #1. #2 is a deeper problem with GWT.
