This patch adds that missing caching functionality. I tested by adding a `System.out.println` to `MethodTypeDesc.ofDescriptor` and it printed nothing locally when running this little program including string concat and lambda with `java Ape` (Note that `java Ape.java` will print gibberish once`, didn't diagnose that one yet): public interface Ape { static void main(String... args) { Runnable a = () -> { System.out.println("asd[" + args[0] + "foo" + args[1]); }; a.run(); } } Before a cache miss call looked like this: https://github.com/openjdk/jdk/pull/20611#discussion_r1721082199 ------------- PR Comment: https://git.openjdk.org/jdk/pull/20627#issuecomment-2296856100
