I tend to agree. An exception would be cleanest. However, an exception must be caught...so you have the additional try/catch logic affecting optimization, no? Of course perf nuts would also want to pre-allocate that exception, since it's really flow control. Dunno if there's any precedent for that in the JVM other than OutOfMemoryError. - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
