For Java 17 the minimum was 7, and with Java 21 the minimum is 8. For 
packages using ant, Maven or Gradle the level is adjusted automatically. 
You can drop the language level, but the package will require the same 
version or higher at runtime.

We should probably provide the minimum language level supported as a 
variable in the /usr/share/java/java_defaults.mk file from java-common.
