Hi, It seems opencv4.3 is built with JRE version 57. Where can I see the JRE version used in the release package? Any old opencv version I can use which is compatible with JRE version 52?

Thanks!

sounds like one of the reasons why you should build opencv libs locally.

I thought I did by doing:

brew install --build-from-source opencv

Usually java is backward compatible(you can still use java.util.vector or applets) unless you use some language features which were introduced later (annotations, lambdas, generics). I doubt opencv uses any of those language features - it should just work.

Just give it a try
