You assumed the switch needs to happen on the JDK. It’s actually that we bought this software that depends on the old version with a perpetual license 18 years ago before every decided SaaS was god so we’ve got another 3 years left before ROI breaks even
Isn’t there an openjdk impl in like every major Linux distro repository?
And so I assume the same would be available for windows?
yes, but that doesn’t help if the software refuses to run on modern java

Some crappy software actively checks for a specific version, and you can’t work around that.
Can you edit the byte code with a hex editor to change that check?
Not if you want support from the vendor :p
Just build the OSS version of java-impl with the patched version number as expected by the shitty software.
