-------------------------------------------------------------------
Perhaps not. All beans will be using the same Batch, and the batch will not be closed until the last release() is called, and so in theory, the work on all beans will be committed at that point. But SFSB instances may have references to the batch left uncleared.
So, with the current change (which only clears the session instance CacheContext on release if there is no transaction active), if we have one user transaction with an invocation on A and an invocation on on B and an invocation on C, then, at commit time, B and C will still have references to the common Batch in their CacheContext fields. Which is probably what we don't want.
This could be fixed by storing in the TSR, not only the Batch instance, but also the K id of the session instance of the first invocation through in the user transaction. Then in release(), rather than choose to remove or not remove the CacheContext based on whether we are in a transaction, do it based on whether or not we are in a transaction and the K id matches.

> Key: WFLY-6498
> URL: https://issues.jboss.org/browse/WFLY-6498
> Project: WildFly
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 10.0.0.Final
> Reporter: Richard Achmatowicz
> Assignee: Paul Ferraro
> Fix For: 11.0.0.Alpha1

>
> Using the EJBClient library, we should be able to do the following from a standalone EJBClient application:
> // create a UserTransaction associated with a clustered server node X
> // make an invocation on an EJB on X
> // make an invocation on an EJB on X
> // commit the UserTransaction
> However, doing so results in this exception which occurs during processing of the second invocation:
