    I have installed IBM iACS 1.1.9.2 on Windows 10.

    What are the Java recommendations for this version?
    Are there font issues on telnet 5250 if you change your java version?

    The getting started guide section on prerequisites simply says java 8 or higher and has some suggested distros of Java
    https://www.ibm.com/support/pages/ibm-i-access-acs-getting-started#3.0

    The updates page at https://www.ibm.com/support/pages/ibm-i-access-acs-updates also lists some suggested distros of Java but doesn't say what version to use.

    To use ACS you need at least the JRE Version 8 on Windows but you can go for higher versions also. 
    At the moment I'm running ACS with OpenJDK Version 16.

    I haven't noticed any differences between Java 8 and OpenJDK 16.

    As far as I understood IBM pointed out under "3.1 Prerequisites (workstation)" that Java 8 is needed to run ACS.

    I did click on the feedback on this site and asked for it to be updated for newer versions of iACS and Java

    Dear Gerald

    In my experience, using IBM Semeru JRE for Windows is quite a safe way to go for running IBM i ACS. This can be a reason why the web page you referred to above was no longer updated for a long time now.
