**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported NullPointerException has been verified in `DashboardCollectServiceImpl.jsonDataFile2map()`. **Root Cause:** When the data file is empty or contains only whitespace, `JSONObject.parse()` returns `null`, and the subsequent `json.entrySet()` call throws NPE. **Impact:** Dashboard crashes when loading empty/corrupted data files, preventing users from viewing historical metrics. **Severity:** Medium — causes runtime exception but only triggered by malformed data files. **Suggested Fix:** Add null check after `JSONObject.parse()` and return an empty map when the parsed result is null. An automated fix proposal can be generated. Reply `/approve` to proceed with PR generation. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
