Java is already 9.0.4… I just tried the same I always did when updating, following the instructions on command line… I get this error below. Trying to update from 4.7.7 to 4.7.8. A problem occurred while detecting installed or update versions - update cannot continue. ---

I am happy I choose to reinstall as this update was more of an upgrade than an update.
