Aias00 opened a new issue, #6741: URL: https://github.com/apache/shenyu/issues/6741
- severity: Medium - files: `shenyu-plugin/shenyu-plugin-proxy/shenyu-plugin-rpc/shenyu-plugin-dubbo/shenyu-plugin-apache-dubbo/src/main/java/org/apache/shenyu/plugin/apache/dubbo/ApacheDubboPlugin.java:69-71` - description: `RULE_CACHED_HANDLE.get().obtainHandle(rule.getId())` returns `null` when the rule handle is absent (cache miss, or rule arrives before handle sync). `CommonHandleCache.obtainHandle` returns null per its contract; `cachedHandle` refuses to store null values. Line 70 `dubboRuleHandle.getTimeout()` NPEs. Same pattern in `ApacheDubboGrayLoadBalance.java:54,57`. - impact: A dubbo request for a rule whose handle hasn't been cached (timing race) throws NPE → 500. - suggested_fix: Default to `DubboRuleHandle.newInstance()` when `obtainHandle` returns null, or null-check. - confidence: Medium - related_existing: none — #5802/#4665 are different paths. --- _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.
