RpcDispatcher: non-reflective method invocations ------------------------------------------------ Key: JGRP-2338 URL: https://issues.jboss.org/browse/JGRP-2338 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Priority: Major Fix For: 4.1.0 Running a native image produced by the GraalVM AOT (ahead-of-time) compiler prohibits the use of Java Reflection. However, RpcDispatcher uses {{java.lang.reflect.Method}} to invoke remote method calls. h4. Goal Provide a mode (in {{MethodCall}}) which doesn't require a {{MethodLookup}} table but rather takes user-provided code (e.g. a lambda) to find and invoke the correct method. This could be done by introducing an additional mode in {{MethodCall}} based on {{ID}} which calls the (user-provided) lambda to invoke a method. The lambda would read the arguments and invoke the method based on the received ID, then return the result.
