Is there a way to fix this issue? I'm using elasticmq version 0.8.12. Thanks

How did you get this? Did you invoke any operations?

[micmicsuarez]

@adamw , sorry for late response.

I have a method inside the JmsListener that process hundred thousands of data. This method downloads the csv file and save each row in a list. After parsing it, we iterate in the list and create an object. It looks like this:

     List sampleObjectList = []
     List numbers = [1, 2, 3, 4, 5, 6, 7, ...']
     numbers.each { number ->
         sampleObjectList << new SampleObject(number: number)
     }
     batchValidateAndSave(sampleObjectList)

We save a batch of objects. I just send a message to the other JmsListener by using the send method of jmsService.

jmsService.send(queue: CustomQueue.MyQueue, [userId: user.id])

[adamw]

So this works now?
