  1. Mikhail Fokanov  Please can the content of this page be converted to English and the header be updated to support the decision log page entry, at the moment, it does not show that this decision has been made.

  2. Marc Johnson The Russian headings was automatically inserted by Confluence. I thought they are supposed to be displayed in user language based on some Operating System values, but Confluence is not so smart. I will correct it.

  3. Please could this be updated to clarify the scope (e.g. is it a recommendation or a requirement, which modules does it apply to) and specifics (e.g. is it the use of log4j2, the use of a specific configuration, or the use of a library that uses log4j2) of this decision.
