Hello! I'm working on class-file decompiler for records and discovered that there's no special flag for generated equals/hashCode/toString (like ACC_SYNTHETIC). This allows determining whether this method was explicitly specified in the source code only by looking into method implementation whether it has an ObjectMethods.bootstrap indy or not. This looks implementation-dependent and somewhat fragile (though, of course, we will do this if we have no other options). We also have a stub decompiler that decompiles declarations only without checking method bodies at all and it also wants to know whether equals/hashCode/toString methods were autogenerated. Finally, other bytecode tools like code coverage may need this to avoid calculating coverage for methods not present in the source.
Is it possible to mark generated methods via ACC_SYNTHETIC or any other flag or add any attribute that can be used to differentiate auto-generated methods from the ones presented in the source code? Having a synthetic mark for auto-generated canonical constructor or accessor methods is less critical (as their bodies could be actually written in the source code like this) but it would be also nice to have it. With best regards, Tagir Valeev.
