Aside from the MQ Java version, you should also consider the Java version as such. Today all Java versions below Java 8 are considered at risk for vulnerabilities and current versions of Java at use throughout the industry are Java 8, Java 11, Java 17, Java 23.
So before using a Java MQ version, you should check the minimum Java version required and make sure that it matches your security requirements

Hi Allen,
I suggest you raise an idea for this: https://www.ibm.com/support/pages/welcome-ibm-ideas-portal.

Anyone have an idea if and when IBM will add the MQ client version to their SMF116 records?
Thanks,

Hello Morag,
It really helped us to find the version from running channel and some of the app has old version of java that will be updated.
Thank you

Hi KP,
The Java version of a network connected IBM MQ Client application is not specifically something to worry about but the MQ version of the application might be, and upgrading that will pull up the required Java version at the same time. You can see this in a number of ways. If the client stays connected to your queue manager for long enough to see it with a DISPLAY CHSTATUS command, then that's nice and easy. Just look for the RVERSION field shown in the output of your command:
DISPLAY CHSTATUS(chl-name) ALL
If it's too short-lived a connection, then you can instead discover this information by collecting accounting records. I'll link some reading material below in case you need to do this step, but hopefully the first command will work for you.
Once you discover the version of MQ in use, make sure that it is within support and not a really old version and you'll be good to go. If you're worrying about an old Java version, then you the same worry may result with an old MQ version. This post: MQ Client versioning may help to guide your thought process there.

Cheers,
