Hello.

I generally prefer to move between and manage documents from the cli - including producing and opening documents in more gui friendly software such as libreoffice...

I have found that often, if I enter libreoffice --calc [insert doc name], or even evince [insert pdf name] I get a few replies from the system letting me know something is running.

My question is, what is this information and does it mean something is off? Is something wrong, or does this just mean the machine is processing something (this laptop is ubuntu-gnome 16.04 lts).
Today's information when opening a document with $ libreoffice --calc was:

javaldx: Could not find a Java Runtime Environment!
Warning: failed to read path from javaldx

(soffice:5445): Gdk-WARNING **: gdk_window_set_icon_list: icons too large

(soffice:5445): Gdk-WARNING **: gdk_window_set_icon_list: icons too large

** (soffice:5445): WARNING **: Unknown event notification 36

** (soffice:5445): WARNING **: Unknown event notification 36

** (soffice:5445): WARNING **: Unknown event notification 34

none of these are actual errors, just warnings.

LO needs java for some parts of its functionality (i always thought some jre was a hard dependency; apparently not) - so you will probably miss that functionality if there's no JRE.

the rest are of no practical interest.

thank you so much

I will need to look into this issue of whether missing a JRE affects anything for me.
