I say that constant method handles *can* be optimized more easily. static final fields can be optimized as well if changing a static field by reflection trigger a VM deoptimization. Anyway, you can store your load-time constant in a static field, initialize it in a static block and use invokedynamic to load it. In the bootstrap method, do a field lookup to get the value and return a constant method handle created using the value. > Helmut > Rémi _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
