Controls Update Notice
Recommended countermeasures forCentralised Controller / Air Conditioning
Control System due to expiration offree support and upgrades for ourcustomers (commercial users) of Java8.
At the end of March 2019, Oracle changed its support policy, which meanscommercial users (*1) must now secure a subscription to access the Java Platform,
Standard Edition (Java SE) for support purposes. This notice recommends
countermeasures that our customers (commercial users) may take, including
securing such a subscription, to maintain Java support updates and to help
protect against security vulnerabilities.
Oracle JAVA SE must be embedded on each commercial user’s computer and web browser
when operating a Mitsubishi Electric centralised controller or air conditioning control systemthat uses a web browser, when using the CSV download tool, and/or when connecting thecentral controller to the internet or LAN. Due to the change in Oracle’s support policy,
Oracle JAVA SE is no longer available for free so this notice explains Mitsubishi Electric’s
recommendations to maintain Oracle JAVA SE support on an ongoing basis.
For more information of Oracle's support policies, please review
Oracle's published "Oracle Java SE Support Roadmap" (*2).

(*1) The monitoring and operation of air conditioning in ofﬁce buildings and other locations are for business use,making users "commercial users". This also applies to our customers of the users of centralised controllers
and comprehensive air conditioning control systems of Mitsubishi Electric.
