Is it possible that your system administrator removed log4j because of the recent security problems?

Hello Jay,

It is my understanding of the question of that you are getting the mentioned warning.

The warning has no functional effect on MATLAB; the only negative impact is the undesirable message. In order to prevent the warning message, you can manually download and install the “Times Roman” font.

You may refer the following link for more information:
