The path /etc/.java is defined in FileSystemPreferences.java [1]. We could probably change it to /etc/java/prefs or /var/lib/java/prefs. But do we really want to deviate from upstream for such a minor cleanup of the /etc directory? Changing the directory means we can no longer use the OpenJDK package as a drop-in replacement of the Oracle JDK, and vice versa. An application using the system store wouldn't find its data after the switch (but this feature is rarely used, so that may be a purely theoretical issue).
