+1 here since we are moving to API/SPI model. For PojoCache integration, I have refactored my code to use some delegation (from a sub-class of TreeCache). So next step is to use Cache implementation directly. There is an integration task for this in 2.0. http://jira.jboss.com/jira/browse/JBCACHE-685 I think it is ok to go ahead now. I suspect there are only few in PojoTreeCache that needs changed (without looking at it first). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959388#...
