# Portability testing across OSes and newer Java versions
# ---
# Regularly check if we remain compatible with other OSes than Linux and if we
# could upgrade to newer versions of Java.
#
# This acts more like an indicator if something is going to break. Our main
# target platform is Linux and we build against it during our regular workflow
# runs. Likewise, we're just testing if we could support newer version of
# Java. We're still taking very deliberate decisions to move to newer (LTS)
# versions of Java.
