Semaphore checking in Synchronous job

[sseaman]

I have a job that runs fine when I run it with the SimpleAsyncTaskExecutor.

When I run it with a SyncTaskExecutor it fails though because in the TaskletStep on line 405 Spring Batch does a semaphore.acquire().

I'm not sure that this should even be executing since the comment right above it states:

// If the step operations are asynchronous then we need
// to synchronize changes to the step execution (at a
// minimum). Take the lock *before* changing the step
// execution.

There doesn't seem to be a check to see if the operation is even an async operation at this point.

I'm wondering if this is a bug? Since I'm running SyncTaskExecutor I would think semaphore's are not needed.

Am I correct in this assumption or do I perhaps have something else going on?

Hi,

I have experienced same. I am launching the job from tasklet step of another job. I have put it in Jira. Just have a lookto URL https://jira.springsource.org/browse/BATCH-1819. It seems to be a bug in spring latest 2.1.8.

Thanks,
