Update Java
It's good to update OpenJDK regularly for security reasons, but check the README.html file that ships with your version of Polarion to make sure that major OpenJDK version updates are officially supported before updating to them.
As of Polarion 19 Oracle Java SE Development Kit 8 is no longer supported.
Backup the Java Keystore before installing OpenJDK and reimport it once it and the Polarion installation are complete.
If you added extra GC related runtime parameters for Java, you will need to update so that they'll work with OpenJDK 11. (If you don't, the Java Virtual Machine may fail to start.)
When installing or upgrading to AdoptOpenJDK 11 (LTS) make sure the default file encoding matches the same encoding used by the previous version of Java.
Not sure how to update your custom GC related runtime parameters?

If you update Java to its latest version you will also have to update the Java path in both the polarion.ini and exec.bat files.
(Both files are located in C:\Polarion\polarion\ by default.)
