Description
This week I fugured out that most of the time dynamic Proxies that perform castings and things like that that have a lot of overhead can be replaced with MethodHandles that are available since Java7. I believe Proxy is used at least in FFI/JNA/JVM code. Also the new API coming in JDK 22: https://openjdk.org/projects/jdk/22/ / https://openjdk.org/jeps/454 is based on MethodHandles. Also invokeExact is supported in Kotlin from several versions ago.

Research direction
Start by locating the Proxy usage in the FFI/JNA/JVM code and reading how its casting behavior is implemented. Compare those call paths with Java MethodHandles, including invokeExact support in Kotlin and the JDK 22 Foreign Function and Memory API references linked in the issue. Done means the relevant Proxy-based paths are replaced without changing their behavior, with performance and compatibility checked.
