Looks like there are some command-line switches: https://stackoverflow.com/questions/49076972/how-can-i-throw-an-exception-for-an-illegal-reflective-access-warning where: "--illegal-access=deny will cause the expected IllegalAccessException or InaccessibleObjectException to be thrown. If you just want the stack traces then --illegal-access=debug is what you are looking for. " would seem helpful in particular... -+ Tatu +- > > -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
