The message hints you are using MacOS ? Which OS release?
(You tagged that you are using R2018b -- thank you for providing that information!)

Don't move the mouse.
Sorry, I could not resist.
When did this start? Directly after installing Matlab or was it an update of the Java runtime? Did you upgrade the OS or Matlab before?

Mine is macOS Catalina 10.15.6.
It started a couple of days ago. I do not recall that I updated either matlab or OS. I tried restarting matlab and computer but still appears every time I re-open matlab. It is really anoyying :(

Note that R2018b is not officially supported on MacOS Catalina; R2018b support tops at at Mojave.
MacOS Catalina had a security update three days ago, December 14th; https://support.apple.com/en-ca/HT212011

Just did the update or Catalina, and problem still the there:(
Also, I made a mistake. My Matlab version is R2018a. Do you think deleting matlab and reinstalling it could solve the problem? Do I have to worry about anything if want to do so?
Thanks for your help by the way!

Also if someone knows a way to metigate the problem somehow, please let me know. I mean something in the settings that could for example suppress this stream of output in the command window.

R2018a was last supported on High Sierra. It is known not to work properly on Mojave or later if your Locale is not set to en-US (US English)
