    [ https://issues.jboss.org/browse/WFLY-6498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13191385#comment-13191385 ] 

Richard Achmatowicz commented on WFLY-6498:
-------------------------------------------

Paul has proposed a simpler, less intrusive fix based on the same idea. It involves injecting the TransactionSynchronizationRegistry diretcly into the Batcher and using that as a repository for Batch associated with a wrapping transaction.

>          Components: Clustering
>    Affects Versions: 10.0.0.Final
>            Reporter: Richard Achmatowicz

> 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:
