Yes, I guess you were missing something. ;-) The service routine inlining is to attack the performance issue brought when Java code calls into VM native services. If the JNI is not a problem, this Java inlining can be not very interesting.
So why can't we optimize native (JNI) calls from Java code using annotations similar to those used to annotate helper's slow call above? Once developer annotates native call with information about it's sideffects we can optimize the call and reduce JNI overhead. ? -- Mikhail Fursov
