gRPC reflection fails with java.lang.NoSuchMethodError

[jasonschroeder-sfdc]

I am troubleshooting connectivity with my BuildFarm services.

I see that ProtoReflectionService is added to the BuildFarmServer.java, but when invoking it, the server logs an exception:

Exception in thread "grpc-default-executor-267259" java.lang.NoSuchMethodError: 'boolean com.google.protobuf.GeneratedMessageV3.isStringEmpty(java.lang.Object)'
