However if you throw an exception on setLeasePeriod(<0) isn't that a signature change? We would have to change some testcases using setLeasePeriod(-1) hoping to disable lease. If you *must* change the API we will need to plan ahead. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3973576#...
