We are introducing a change in JDK/JRE packages of our distro. This is triggered from the way a JRE is build in modern versions of Java (>9). To sum it up instead of having JDK and JRE packages coexist in the same system we will be making them conflict. The JDK variant package includes the runtime environment to execute Java applications so if one needs compilation and runtime of Java they need only the JDK package in the future. If, on the other hand, they need just runtime of Java then JRE (or jre-headless) will work. This will (potentially) require a manual user action during upgrade: if users have both JDK and JRE installed the can manually install the JDK with pacman -Sy jdk-openjdk and this remove the JRE related packages. if users have both JRE and JRE-headless they will need to choose one of them and install it manually since they would conflict each other now. If they only have one of the JDK/JRE/JRE-headless pacman should resolve dependencies normally no user action is needed. The above are also valid for Java 17 and Java 11 packages as well but not for Java 1.8 since they don’t support modules. -- Leonidas Spyropoulos Developer & DevOps PGP: 59E43E106B247368
