TBox and Java Log4shell: not affected

"A vulnerability in Java software has kept IT security personnel awake since the weekend. Millions of applications are likely affected, including those from Apple, Tesla, Minecraft, and Google." is an excerpt that appeared in NZZ on December 13, 2021.
That raises the question of whether the RTU system TBox is also affected by this incident.
The TBox is not affected by this vulnerability (Log4shell) as the mentioned tool is not used.
