[Bug] 3.3.0-beta2 update to beta3, exception : module java.base does not "opens java.util" to unnamed module about dubbo

[aofall]

In 3.3.0-beta.2 the default serialization is fastjson2, in 3.3.0-beta.3 the hessian serialization back and set as default serialization by #13974

It caused by hessian serialization. You can temporarily set the serialization as fastjson2 again. The issue of hessian serialization with newly JDK may solved in the future.

You can modify the settings according to the actual situation, and be aware that there may be unexpected issues with fastjson2 as well.

dubbo:
  protocol:
    serialization: fastjson2
    prefer-serialization: fastjson2,hessian2

We had a meeting to discuss this problem, the reason is that the adaptation of hessian2 with high jdk version is difficult, so we can use fastjson2 first

Already fixed in apache/dubbo-hessian-lite#70

Please wait Hessian Lite 4.0.1 and Dubbo 3.3.0-beta.4 being released. BTW, in order to solve it, you need to upgrade both client and server side.
