[Bug 283291] Re: JUnit does not run with JDK5 because it is compiled with JDK 6

[Emmanuel Bourg]

Java 9 is no longer able to generate Java 5 compatible bytecode and
it'll be worse with every new Java release according to JEP 182. This
means every time this package is rebuilt the runtime requirement becomes
higher than previously. There is nothing we can do since we don't keep
old compilers.
