It can be just a compiler change (a JLS change) if invokedynamic is used instead of invokevirtual for doing the re-targeting. But as currently specified by the JEP 193, yes, the semantics of invokevirtual is enhanced so it requires to bump the major version to 53.0 > > (Yes, changing instruction semantics causes a bump.
