Aias00 opened a new issue, #6749: URL: https://github.com/apache/shenyu/issues/6749
- severity: Medium - files: `shenyu-plugin/shenyu-plugin-mcp-server/src/main/java/org/apache/shenyu/plugin/mcp/server/transport/MessageHandlingResult.java:87-98` - description: `getResponseBodyAsJson()` does `new ObjectMapper().writeValueAsString(responseBody)`. When `responseBody` is a `McpSchema.JSONRPCMessage`, serialization uses a vanilla ObjectMapper without the MCP Jackson module that the configured `JacksonMcpJsonMapper` would apply. MCP sealed-record/polymorphic types may serialize incorrectly. - impact: Streamable HTTP responses may be malformed when the body is an MCP schema object. - suggested_fix: Reuse the transport's configured `McpJsonMapper`/`ObjectMapper` instead of `new ObjectMapper()`. - confidence: Medium - related_existing: none — PERF-22 is perf only. --- _Identified during the 2026-08-02 deep re-scan; full list in [`docs/scan2-2026-08-02/06-medium-tiers.md`](docs/scan2-2026-08-02/06-medium-tiers.md)._ -- This is an automated message from the Apache Git Service.
