As it obtains a bit more coding, I had filled the [JDK-8323169](https://bugs.openjdk.org/browse/JDK-8323169) - [ j2dbench need constant updating of javac source/target ](https://bugs.openjdk.org/browse/JDK-8323169)  and will be happy to fit it for jdk asap once this direct fix bubbles to jdk21

Many swing demo or benchmarks like J2DBench, J2DDemo & RenderPerf are compatible accross jdk (8-23).
Having an openjdk common or shared tools could be great
