Has Ventura changed how CWD is set when executing a jar file?

Six years ago I wrote a Java App that assumed (possibly incorrectly) that the current working directory for the JVM would be set to the directory containing the jar file. So when I installed the app I put it into a new directory under documents. This has worked fine on Windows and MacOS through a number of system upgrades until Ventura where suddendly the app failed because it was unable to locate its database. After much thrashing around I discovered accidentally that if I moved the directory containing the jar file to some location other than under documents or desktop, it resumed normal execution.

I haven't tested all the subdirectories under my home directory other than documents and desktop. What I did was simply add a new subdirectory to my home directory. I should also say that I upgraded the jre to the latest one, but that did not solve the problem.
