No chance to reload from the cache loader as the user thread is already past the interceptor. No, eviction should still respect the locks, of which what it is doing now if I am correct. The question is the lock wait time, whether it is 0 or the regular setting. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3980904#...
