## Summary - Fix deadlock when using `SynchronousExecutorService` with split + aggregate in transacted routes - CAMEL-23030 changed `scheduleSync(task)` to `schedule(task)` for `SynchronousExecutorService`. The aggregated exchange loses the transacted flag (`Exchange.copy()` doesn't preserve it), so this new branch is always taken. `schedule()` queues the completion task, but the surrounding transacted split creates nested `await → executeFromQueue` cycles where `Pipeline.scheduleMain()` queue swapping makes the task unreachable — deadlock. - Fix: process the completion task inline via `processor.process(exchange, callback)` for `SynchronousExecutorService`, bypassing the reactive queue entirely. No deadlock, no stack overflow. ## Test plan - [x] `SplitAggregateInChoiceSynchronousExecutorTest` — 3 tests covering non-transacted, transacted, and transacted+choice scenarios - [x] `SplitAggregateSynchronousExecutorStackOverflowIssueTest` — CAMEL-23030 regression guard still passes - [x] `SplitAggregateStackOverflowIssueTest` and `SplitAggregateParallelProcessingStackOverflowIssueTest` — existing tests pass -- This is an automated message from the Apache Git Service.
