There are may reasons to not to do this change. At least not to do this as it is specified. Where is best place to discus? Discussion already started at java-project@xxxxxxxxxx.[1] Please advice, J.

= Proposed Self Contained Change: Decouple system java setting from java command setting = https://fedoraproject.org/wiki/Changes/Decouple_system_java_setting_from_java_command_setting Change owner(s): * Michael Simacek <msimacek AT redhat DOT com> * Mikolaj Izdebski <mizdebsk AT redhat DOT com> Alternatives can be used to specify which Java installation should be the default for the system. Currently, changing the default java command causes not only a change to the /usr/bin/java symlink, but also affects the which runtime is used for system installed Java applications. We propose introduction of separate setting for system-wide java applications. == Detailed Description == Fedora allows parallel installation of multiple Java runtime environments and it uses alternatives mechanism to allow the user to switch between them. JDK packages provide a set of alternatives symlinks for it's executables. The java symlink is used to determine the java command (/usr/bin/java), but also determines which runtime environment is used to run system-wide Java applications installed from RPMs, such as maven or eclipse. While in theory different Java runtime environments are drop-in replacements for each other, in practice some of the applications may stop working properly. Users usually install alternative JDKs in order to run their own applications and don't expect that changing the java command will have effect on the system applications. By introducing a separate setting for system-wide java, we would avoid this problem. We propose specifying default Java runtime for RPM-managed applications in /etc/java/java.conf (this is already possible, but not currently used). Administrators would still be able to override the system default if they need to. == Scope == * Proposal owners: Adjust javapackages-tools to provide default Java setting in /etc/java/java.conf * Other developers: N/A (not a System Wide Change) * Release engineering: https://pagure.io/releng/issue/6831 * List of deliverables: N/A (not a System Wide Change) * Policies and guidelines: N/A (not a System Wide Change) * Trademark approval: N/A (not needed for this Change)
