Well, no it hasn't. Things like Jaxb, for example, have always existed in the JDK since they were introduced (java 1.2 in Jaxb's case). XML processing code compiled with jdk5 (circa 2004) still worked fine on java8, for example, with zero code or dep changes. Suddenly that assumption is broken with java9.

It was just an admittedly contrived scenario where the upgrade path to jdk9+ wasn't as straight forward as just adding deps to maven and calling it a day, since you may not be aware of all code interactions, depending on the system you're upgrading.
Your program might even have a dep on some jar that was compiled under jdk4 and the author and source are nowhere to be found (or went out of business a decade ago)... and suddenly it breaks under java9. Things like that are largely what prevented mass adoption of jdk9 immediately.
