Aias00 opened a new issue, #6580: URL: https://github.com/apache/shenyu/issues/6580
## Description `ObjectMapper` construction is expensive (builds TypeFactory/serializers/mixins) and is constructed per request. The project already has `org.apache.shenyu.common.utils.JsonUtils.MAPPER`. ## Location ``` shenyu-plugin-mcp-server/.../McpServerPlugin.java:710 (new ObjectMapper().writeValueAsString(errorBody)) shenyu-plugin-mcp-server/.../transport/MessageHandlingResult.java:93 (new ObjectMapper().writeValueAsString(responseBody)) ``` ## Impact Per-MCP-request ObjectMapper allocation on top of the serialization itself. ## Suggested fix Reuse a static `ObjectMapper` (or `JsonUtils`). Line 710 also uses `errorResponse.getBytes()` (default charset) — use `StandardCharsets.UTF_8`. ## Related existing issue(s) None _Identified during the 2026-08-02 audit; full list in [`docs/issue-candidates-2026-08-02.md`](docs/issue-candidates-2026-08-02.md)._ -- This is an automated message from the Apache Git Service.
