Bump grpc-protobuf from 1.32.2 to 1.53.0 in /examples

[dependabot]

Bumps grpc-protobuf from 1.32.2 to 1.53.0.

Release notes

Sourced from grpc-protobuf's releases.

v1.53.0

New Features

• googleapis: Allow user set c2p bootstrap config (#9856)
• xds: Add contain and stringMatcher in RouteConfiguration (#9845)
• core: Add grpc-previous-rpc-attempts to the initial response metadata (#9686)
• servlet: Implement gRPC server as a Servlet (#8596)
• authz: Implement static authorization server interceptor (#8934)

Examples

• servlet: Add servlet example (#8596)

Bug Fixes

• xds: Update xds error handling logic. Specifically:
  • When the ads stream is closed only send errors to subscribers that haven't yet gotten results
  • Timers to detect missing resources don’t start until the adsStream is ready (#9745)
  • Call subscriber onError callback when xds client fails to connect to server (#9827)
• core: Delay retriable stream master listener close until all sub streams are closed. This fixes the call executor lifecycle and prevents potential RejectedExecutionException. (#9754)
• core: Free unused MessageProducer in RetriableStream (#9853), fixing a Netty buffer memory leak for cancelled RPCs
• api: Fail with NullPointerException when a Metadata.Marshaller returns null bytes (#9781). This would previously cause a NullPointerException later during the RPC. Now the return value of the Marshaller is checked immediately, to help find the broken Marshaller

Behavior Changes

• xds: Disallow duplicate addresses in the RingHashLB. (#9776)
• xds: EDS weight sums are allowed up to max unsigned int (was max signed int) (#9765)
• xds: Drop xds v2 support (#9760)

Dependencies

• JUnit upgraded to 4.13.2
• bazel: Dropped support for Bazel 4. We track the two most recent major versions of Bazel, Bazel 5 and 6. Bazel 4 may still work, but we are no longer testing it
• bazel: Include Tomcat annotations dependency for @Generated as used by autovalue (#9762). Necessary for building xds and rls on Java 9+
• bazel: Export deps from Maven Central-specific stand-in targets (#9780). Some Maven Central artifacts are a combination of multiple Bazel targets, like grpc-core is composed of //core:inprocess, //core:internal, //core:util, //api. There is a “//core:core_maven” target used by maven_install that uses the other targets. Previously the target used runtime_deps to discourage their use by Bazel users, but that could cause compilation failures from lack of hjars. These targets now use exports

v1.52.1

Bug Fixes

• xds: Fix an internal bug in xds resource subscription that might cause xds stream not accepting response update for that resource type entirely. (#9810)

v1.52.0

gRPC Java 1.52.0 Release Notes

grpc-xds starting with 1.51.0 had a regression where resources might stop receiving updates. The trigger could happen hours or days after the binary had started. xDS users should avoid this release and use 1.50.x until patch releases with the fix are available. grpc/grpc-java#9809
