I have no experience in upgrading Java versions or the corresponding code changes required. I have witnessed runtime differences, related to performance and GC behavior, from Oracle 8 to OpenJDK 8 that were unexpected enough to warrant temporarily sticking with Oracle in exactly one case.

That is eons ago, in Java 8 there were indeed differences between Oracle JDK and OpenJDK, this in no longer true since Java 10, even less so in Java 16.

Now, Java like C or C++, enjoys multiple implementations, so even across OpenJDK, J9, Azul, PTC, Aicas,..., there will be differences.
