Then I think we should probably patch GenerateJLIClassesHelper to call `MethodType.methodType(void.class)` (or any other method type) twice somewhere. The 2nd call ensures there will be a method type lookup, which covers the missing code path that causes the problem. ------------- PR Comment: https://git.openjdk.org/jdk/pull/29678#issuecomment-3888726353
