In that case, you have to encode those methods as live `MethodHandle` objects, passed to the generated class with `defineHiddenClassWithClassData` (just pass the class data object) They can be retrieved in generated code with a CONDY using `MethodHandles.classData`. (This is how the MethodHandle LambdaForm classes referred to other MethodHandles) ---- You don't really need to worry about experimenting with bytecode generation right now. This patch as is is very good, and tier 1-3 tests pass. Bytecode gen is aimed at more complex scenarios with multiple constants and various types of arguments instead of this simple concat case. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20253#issuecomment-2240961431
