Ok, I fixed the interpolator so that it won't throw an exception when an improperly formatted message comes in. Just so you know, though, you really should be constructing log messages more like | log.info("Here's my potentially dangerous value: #0", myValue); | instead of | log.info("Here's my potentially dangerous value: " + myValue); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4012571#...
