Man pages (and info pages) installed outside of /usr/share/doc for slotting reasons or otherwise handled via MANPATH/INFOPATH need to be compressed via explicit `docompress`. I've not checked dev-lang/openjdk-bin It looks like OpenJDK needs to do this: ``` $ ls -1 /etc/java-config-2/current-system-vm/man/ jar.1 jarsigner.1 [...] ```
icedtea, icedtea-bin, and openjdk-jre-bin all seem to set MANPATH too, so including them.
