> During project builds using calcite-core, the following warning shows up:
> {code:java}
> WARNING: An illegal reflective access operation has occurred
> WARNING: Illegal reflective access by com.google.protobuf.UnsafeUtil
> (file:/Users/amannmalik/.gradle/caches/modules-2/files-2.1/com.google.protobuf/protobuf-java/3.6.1/d06d46ecfd92ec6d0f3b423b4cd81cb38d8b924/protobuf-java-3.6.1.jar)
> to field java.nio.Buffer.address
> WARNING: Please consider reporting this to the maintainers of
> com.google.protobuf.UnsafeUtil
> WARNING: Use --illegal-access=warn to enable warnings of further illegal
> reflective access operations
> WARNING: All illegal access operations will be denied in a future release
> {code}
> This is due to the Avatica dependency on a version of protobuf-java that
> suffers from the already documented and resolved issue:
> [https://github.com/protocolbuffers/protobuf/issues/3781]
> Simply upgrading the dependency version to the latest (3.17.1) passes the
> Avatica build and results in removal of the warning.
