Describe the bug

Code that is generated with the new protobuf release 3.22.0 does not work in Quarkus.

The exception looks somewhat like this:

Caused by: java.lang.IllegalAccessError: class <some-generated-protobuf-code> tried to access method 'com.google.protobuf.LazyStringArrayList com.google.protobuf.LazyStringArrayList.emptyList()' (<some-generated-protobuf-code> is in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @4f5c30b1; com.google.protobuf.LazyStringArrayList is in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @6d4a65c6)

protobuf code generated w/ versions < 3.22.0 referenced the public static field com.google.protobuf.LazyStringArrayList#EMPTY, the static method emptyList() is package-protected before 3.22.0.

In 3.22.0 emptyList() became public static and code generated w/ 3.22.0 references that method.

However, the Quarkus bom enforces protobuf-java to 3.21.9, so code generated w/ 3.22.0 won't be able to access the package-protected method emptyList().

I suspect, a bump of protobuf to 3.22.0 in Quarkus (at least on main) should help here.
