illegal reflective access operation

[MorinRemi]

com.google.datastore.v1.client.RemoteRpc does an Illegal reflective access when running on Java 11 (and probably any above java 1.8) resulting in error being sent right to system error.

The offensive line is https://github.com/GoogleCloudPlatform/google-cloud-datastore/blob/a23940d0634d7f537faf01ad9e60598046bcb40a/java/datastore/src/main/java/com/google/datastore/v1/client/RemoteRpc.java#L72

I posted an update to googleapis/google-http-java-client#367 which would remove the need for this hack entirely.

We can fix this but we need a release of google-http-java-client first.

[elharo]

http-java-client released, proceeding

How to fix this? I am using below dependency for datastore
org.springframework.cloud:spring-cloud-gcp-starter-data-datastore:1.1.2.RELEASE

[elharo]

Make sure you're using the latest version of the datastore and http clients. libraries-bom 5.6.0 should give you this.
