v1.62.2

gRPC Java 1.62.2 Release Notes

Note that this is the initial 1.62.x release

API Changes

• services: Remove io.grpc.services.BinaryLogs, which was deprecated since 2021. io.grpc.protobuf.services.BinaryLogs should be used instead (#10832).
• Allow users outside of io.grpc.xds package to create custom xDS resources (#10834) (6d96e65)

New Features

• api:Add ClientTransportFilter. Similarly to ServerTransportFilter, this will provide an observability hook and it allows direct modification of the transport's attributes. (#10646)

Improvements

• java_grpc_library.bzl: Add support for Auto Exec Groups (cb03bd2). This is mostly a behind-the-scenes change to adjust to the newer way Bazel operates
• java_grpc_library.bzl: Support runfiles for protoc and the plugin (65a6b3b). Neither binary uses runfiles, but the task will be ready if they need to in the future
• xds: Add EC key support for XdsChannelCredentials/XdsServerCredentials (100d5a5)
• binder:Change log level from WARNING to FINER for expected exception during close with error, to reduce log spamming (#10899) (7ba0718)

Bug Fixes

• xds: Fix a bug in WeightedRoundRobinLoadBalancer policy that could raise NullPointerException and further cause channel panic when picking a subchannel. This bug can only be triggered when connection can not be established and the channel reports TRANSIENT_FAILURE state. (#10868)

Dependencies

• The protoc plugin no longer supports macOS Big Sur (macOS 11). Binaries are now built using Monterey (macOS 12)
