## Which Issue(s) This PR Fixes Fixes #10990 ## Brief Description `PopLongPollingService.notifyMessageArrivingFromRetry` dereferences the properties map without checking for null. Retry dispatch requests can legitimately have no properties, causing an NPE in the reput thread and stalling broker-wide dispatch. Return early when properties are absent, matching the existing behavior for a retry message without an origin group. ## How Did You Test This Change? - Base SHA: `$(git rev-parse develop)`. - Confirmed current code calls `properties.get(...)` unconditionally. - `git diff --check` passed. - Maven is unavailable in this environment, so the required test suite was not run; CI should validate. ## Risk Low; only prevents a null-properties crash and skips notification when no origin group can be determined. AI-assisted contribution; implementation and verification performed against current `develop`. -- This is an automated message from the Apache Git Service.
