Hi @MikeArbon,
Oracle announced the end of public updates for Oracle JDK after January 2019. IFS Middleware Server has Oracle JDK included in it and you are only licensed to use it for IFS Middleware Server. You are not allowed to use the Oracle JDK included in IFS Middleware Server for IFS Applications functionality running on Java outside of IFS Middleware Server, such as the Print Agent, IFS Report Designer etc.
Assuming you have an updated version of IFSAPP9 that was released after 2019 January, please download and use OpenJDK for other tools such as Print Agent. You should never update the Java version of IFS MWS manually as all updates will be provided by IFS.
Regarding the version, check the Java version of the JDK included in IFS Middleware Server and use an equivalent version for external applications as well so that there won’t be any compatibility issues. You can open a command line from \\<IFS_HOME>\mw_home\java
folder and run java -version
command to find the Java version of IFS Middleware Server.
I have also attached the bulletin published by IFS back in 2019 regarding the end of public updates for Oracle JDK. It has some more important information.
Hope this helps!
