Ok Hotspot guys, I have a challenge for the JIT. I want to basically do this:
try { ... } catch (Exception e) { if (!(e instanceof SomeException)) throw e; ... handle e as SomeException } instead of explicitly adding exception-handling for SomeException. There's a few reasons for this: * Wiring up exception-handling in method handles is rather cumbersome. If I could do it with a single wrapper it would make my life easier. * Similar to the "multicatch" problem in Java 7, I often want nearly the same boilerplate code for multiple exception types. * Because Ruby is dynamically typed, we can't statically determine the *actual* expected exception type at compile time, and so we must do a bulk catch with type checks. My question, then, is whether Hotspot can see through this (assuming everything inlines) and see that although we're doing a bulk catch only certain cases *actually* handle the resulting exception. Thoughts? - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
