Why am I receiving this sort of error is it due to incompatible versions of jdk and compiler?

Question

I have a program in java in eclipse 2022-06. I had realized that the jre and compiler versions were different versions as soon as I updated both of them to 1.8 the error disappeared but somehow it has re appeared again and I don't know what could be causing this.

Is it some kind of setting or incompatibility with java versions? I would like to use Java 8 on this project.

Answer 1

Please add it to your startup

--add-opens java.base/java.lang=ALL-UNNAMED

can solve the problem.

For details, you can refer to https://www.cnblogs.com/IcanFixIt/p/7144366.html But it is a Chinese website and you may need to translate it.
