I don't think there's anything super surprising about running on Java 8. I would be more worried if she said Java 4! Java 11, the next long-term support release after Java 8, came out late last year, and there were a lot more breaking changes between 8 and 11 than there were between 7 and 8. I had to a lot of dependencies, especially the ones that use reflection heavily (Mockito and Lombok come to mind!). Meanwhile there are still young Java programmers who think that since 8 is the newest and sexiest thing, everything has to be written using lambdas and streams.
