gRPC Java 1.85.0 Release Notes

netty: Support never-indexed metadata keys (#12976) (e9a8c2b). High-cardinality metadata values provide little compression benefit and can churn the server's dynamic HPACK table. Adds NettyChannelBuilder.neverIndexMetadataKey() and neverIndexMetadataKeys() so callers can mark selected outbound metadata keys for HPACK's never-indexed literal representation.
binder: Add Context-based hasPermissions() to SecurityPolicies and deprecate the PackageManager version.

xds: allow wildcard listener port in LDS (5fda0c7). It now accepts a port of 0 in the LDS listener address as matching any port.

xds: Make RawMessageClientInterceptor conditional on ext_proc flags (#13015) (e58489f). Fixes a bug that caused empty payloads on retry attempts for regular xDS channels.
core: Reset configSelector on realChannel while entering IDLE state (#12832) (fc43144). Because of a bug in the config selector, when ManagedChannel entered IDLE state due to resource deletion on the xDS control plane, the channel stayed stuck in IDLE state even after the resource came back online and a new rpc was executed.
core: Gracefully handle GOAWAY frames with unrecognized error codes (#13035) (b3ae801). When a server or proxy sent a GOAWAY with an unrecognized HTTP/2 error code, such as 70007 from Apache httpd, Netty transport clients logged NullPointerException: Http2Error cannot be null for GOAWAY and RPCs could hang until their deadline. Such codes are now treated as INTERNAL_ERROR, so the transport shuts down cleanly.

netty: make hostname verification configurable (#13002) (2858db2). This configures HTTPS endpoint identification in GrpcSslContexts and updates ClientTlsHandler to preserve an explicit empty-string opt-out. A null algorithm still falls back to HTTPS, retaining hostname verification for custom contexts that do not select an algorithm.
bazel: Adopt proto_lang_toolchain for java_grpc_library() (#12994) (c9ee3f8). java_grpc_library and java_lite_grpc_library now invoke protoc through Protobuf's proto_lang_toolchain instead of always using @com_google_protobuf//:protoc. They now use the same protoc and protoc options as java_proto_library.

api: Implement custom events framework in gRPC-Java server (#12980) (dd00881). This adds triggerEvent/onEvent APIs to ServerCall and ServerCall.Listener. This allows events to be triggered on the ServerCall and be delivered as a listener callback.

Upgrade protobuf for bazel from 36.0 to 36.0.bcr.1 (#13013) (9799887)
netty: Upgrade Netty to 4.2.17 (#13036) (61b910b). netty-tcnative remains at 2.0.81.
