It's easy to be fooled by the nice looking tracef API; can you see what's wrong with the next method? log.tracef("%s: Committing view %s", cacheName, viewId); [solution below] The signature for such a tracef method is tracef(String format, Object param1, Object param2); so integers, booleans, etcetera.. will be boxed into objects. _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
