[jboss-jira] [JBoss JIRA] (AS7-6029) Recovery not fully triggered when distributed transaction falls down at prepare phase of 2PC

The QA team has certain testcases (in an internal git repo) which exposed non-functioning of remote EJB transaction recovery functionality:

https://issues.jboss.org/browse/AS7-6029
https://issues.jboss.org/browse/AS7-6030

Investigating these failures led to enhancements in EJBCLIENT project and bug fix in Narayana project. With these fixes/patches, the tests are now passing. The Narayana project is going to be released tomorrow (Tom is waiting for one other fix to be completed before doing the release, which he expects to be done by tomorrow). Once that bug fix is released tomorrow, I'll be sending a PR to EAP repo to bring in the new versions for Narayana and EJB client projects and do necessary upgrades to integrate that new version.

> It looks like recovery process is not fully triggered on a distributed transaction when the transaction falls down at prepare phase of 2PC. In the new crash recovery tests over propagated transactions only one of two servers recovers from the crash, but the other keeps an unfinished tx in its tx log. 
> It corresponds to prepareHaltClient and prepareHaltServer test methods of org.jboss.as.test.jbossts.crashrec.txpropagation.TxPropagationCrashRecoveryTestCase, see JBQA-2604 for general description of the new tests. The prepareHaltClient test crashes the server which initiated the transaction, while as the prepareHaltServer test crashes the second server.
> The tests are written against EAP6.x branch, so for reproducing this it is needed a built server from the 7.1 branch of AS7.
> Steps to reproduce.
> 1. git clone -b as7 git://git.app.eng.bos.redhat.com/jbossqe/eap-tests-transactions.git
> 2. cd eap-tests-transactions
> 3. git checkout tx_propag_crashrec_tests
> 4a. mvn clean verify -Dtest=TxPropagationCrashRecoveryTestCase#prepareHaltClient -Djboss.dist=<path to jboss-as-7.1.3.Final-SNAPSHOT>
> or
> 4b. mvn clean verify -Dtest=TxPropagationCrashRecoveryTestCase#prepareHaltServer -Djboss.dist=<path to jboss-as-7.1.3.Final-SNAPSHOT>
> The logs of prepareHaltClient run attached to this jira.
