gRPC Java 1.17.1 Released

[Jihun Cho]

GRPC Java 1.17.1 is released and available on Maven Central. It is a patch release to the unannounced 1.17.0. All users are encouraged to use 1.17.1 instead of 1.17.0, because 1.17.0 has an issue with the gRPC LB handling that was not resolved before SRV lookup was enabled. This behavior is disabled by default to restore 1.16.x behavior.

Bug Fixes

• Bazel users should no longer see “java.util.ServiceConfigurationError: io.grpc.LoadBalancerProvider: Provider io.grpc.util.SecretRoundRobinLoadBalancerProvider$Provider not found”. The workaround for 1.17.0 to add a dependency on @io_grpc_grpc_java//core:util is no longer necessary (#5114)

Behavior Changes

• core: SRV records are no longer queried by default when doing DNS lookups. This restores the 1.16.x behavior. This avoids a bug which would in the future make it hard for existing services to enable gRPC LB (#5131)
