Consider bumping protobuf-java to 3.22+

[n1x0l4s]

Building the project, I get class access errors, like protocolbuffers/protobuf#11986

the related commit is protocolbuffers/protobuf@c658e27

I can't reproduce the problem when building project, What's your env information?

[n1x0l4s]

Fresh clone from branch develop with aliyun's maven mirror, the OS is Windows, the build produced emptyList() is not public in LazyStringArrayList; cannot be accessed from outside package and thus searched for a bit and provided related protobuf commit. Would you elaborate what other environment details needed to be addressed?

[KomachiSion]

I use linux sys or mac sys to do build with jdk8 and jdk11. It works well.

The maven mirror is default open repo.

[KomachiSion]

I don't has window sys and no use window sys to build. Need community help to test.

About the protobuf-java version, If upgrade 3.22+ has no compatibility issues, It can be upgrade without immediatly.

[n1x0l4s]

For now leave the issue open as force loading protobuf-java 3.22.2 here on my local dev machine solves the issue. I suggest closing this after verifying upgrade compatibility.

Welcome submit PR.

Upon further inspection, this non issue is local since my former build generated entity from protoc 3.22 which has compability conflits with protobuf-java 3.21.11. The protoc maven plugins were locally masked by local maven profile settings.
Since no .emptyList() from protobuf project is being used in this code base, the upstream change has no affect, thus closing the issue.
