Since the addition of the invokedynamic bytecode in Java 7, the JVM has had only one tool to put user logic in control of linkage decisions. An incredible tool but one with some sharp corners and overhead for simple use cases. With the advent of JDK 11, there's a new tool: Constant_Dynamic that brings JSR292-style user control to the world of constants. This session will overview the new tool, how it works, highlight some important use cases, and discuss possible enhancements.
