Goal

How does configuring multiple receive threads affect JMS Adapter retries ?

By default the JMS Adapter uses only one receive thread.

However to improve performance, the adapter.jms.receive.threads property can be tuned to allow multiple inbound poller receive threads.

When JMS Adapter has "adapter.jms.receive.threads" configured to a value greater than 1, it means there are multiple independent consumers from a JMS queue that can trigger a composite instance.

Because each of these threads is independent, it can lead to apparently confusing retry polling intervals for the JMS Adapter.

This document gives an annotated comparisons of how the retry/backoff works when the Adapter has 1 or 2 receive threads.
