📄 Description

Previously, only sourceCompatibility and targetCompatibility were used, and they might cause issues like NoSuchMethodError when a newer javac compiles with -target older_release.

Note: it is good to use a new an up to date javac to avoid issues in the compiler itself, so having a proper -release .. configuration is vital.
