If you read the mentioned docs carefully, the JRE can be changed **to compile and run test projects**  
However, katalon himself still needs openjdk8 to run (I think the windows version came with an embedded java for runtime)  
there is no mention there to **upgrade** java, only to use an alternate JRE rather than the default set for OS on linux (or other than the embedded version for mac and windows)
