Proposed fix: [Anthropic Java SDK Bedrock/Vertex backends] AnthropicException 'Token counting is not supported for Bedrock.' / 'Batch API is not supported for Vertex.' / 'Service is not supported for
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Keep token counting/batches/models on the first-party client (or use the cloud provider's native batch/count APIs); on Vertex use messages and count_tokens only.
Option: Route unsupported operations elsewhere [evidence: documented_workaround]
Steps:
1. use AnthropicOkHttpClient (first-party) for countTokens/batches/models
2. or provider-native APIs
Expected: No AnthropicException
