Note that this is almost completely useless for now, when openjdk is built a separate store path containing only the jre will be built but it will not be added to the environment nor as a gc root. If you want to install just the jre, for now build openjre (which uses the jreOnly parameter). Once multiple outputs are more feature-complete, this should hopefully be useful and remove the need for the jreOnly parameter
