1. OS type and version: Linux
2. Java version: 17
3. bigtable version(s): 2.58.1 and 2.67.0

#### Steps to reproduce

1. To resolve the CVE-2025-55163 with grpc-netty-shaded upgraded its version to 1.75.0
2. Upgrade Bigtable version as well to latest 2.67.0
3. With these changes adminClient.exists(tableName) returns error

#### Code example
BigtableTableAdminClient adminClient;
adminClient.exists(tableName)

#### Stack trace

#### Any additional information below
We would request you to release the latest version of Big Table that do not have any vulnerability in grpc-netty-shaded.

Thanks!

从 java-bigtable 依赖配置以及 issue 中描述的 adminClient.exists(tableName) 入口点开始。使用 grpc-netty-shaded 1.75.0 重现 NoSuchFieldError，然后验证依赖升级能够消除漏洞，同时不会破坏 Bigtable 调用，并支持发布 release。
