Hi Gabor.
Yes - you certainly can, and you must from FC11:
https://www.ibm.com/docs/en/informix-servers/14.10?topic=overview-whats-new-in-informix#concept_v1410xc11__1410xc11_java_removal
I have found installing Informix product continues to need JRE 8, whereas HQ now wants JRE 11 or later (we are using 11):
https://www.ibm.com/docs/en/informix-servers/14.10?topic=guide-whats-new-in-informixhq#new240_ifxhq__admin_240
If using Linux, install both Open JDK "headless" JRE 8 and a later version using yum, dnf or apt-get. They will then be kept up-to-date with the OS. Set the later version as the default for HQ, and set your environment to JRE 8 only when necessary during an installation.
You should then tar/gzip/rm $INFORMIXDIR/jvm in older versions so it's not reported as a vulnerability.
