[JBoss JIRA] (JBTM-949) Automate the verification of trace output from the XTS crash recovery tests

Automate the verification of trace output from the XTS crash recovery tests
---------------------------------------------------------------------------
Key: JBTM-949
URL: https://issues.jboss.org/browse/JBTM-949
Project: JBoss Transaction Manager
Issue Type: Enhancement
Security Level: Public (Everyone can see)
Reporter: Paul Robinson
Assignee: Paul Robinson
Fix For: 5.0.0.Final
Currently it is very difficult to verify the trace output from the XTS crash recovery tests. With the current code it is infeasible to run multiple servers as the trace output will span many files making it difficult to establish the correct order in which events occurred.
I think, the following changes will make the test verification automatic and the tests scalable to many participants:
# Carry out assertions in Byteman as the test progresses. Assertions at Runtime should be more flexible as more info is available.
# Each participant is concerned only with the correctness of their own participation. This is key to scalability to many participants.
# Anything that can't be solved by the above is dumped to one trace file per server and is hopefuly simple enough for scriptable post-verification.
I think my idea needs prototyping first to check that it is feasible in practice.

[JBoss JIRA] Created: (JBTM-837) Transaction deadlock when NoSuchElementException is thrown from AsyncStore.doWork()

Transaction deadlock when NoSuchElementException is thrown from AsyncStore.doWork()
-----------------------------------------------------------------------------------
Key: JBTM-837
URL: https://issues.jboss.org/browse/JBTM-837
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.14.0
Environment: Ubuntu 64-bit Linux/JBoss JTA 4.14.0/Hibernate 3.6.1/Infinispan 3.4.0.CR2/Spring 3.0.5/MySQL 5.1
Reporter: Tom Waterhouse
Attachments: arjuna-deadlock-trace.txt, default-jbossts-properties.xml
Our product has a scheduled job that runs every 30 minutes. Callable instances are added to an ExecutorService instance which is currently configured for 16 threads.
Our JBoss JTA implementation is using CacheStore as the object store (default-jbossts-properties.xml attached).
After some time a NoSuchElementException is thrown from AsyncStore.doWork(). That exception is somehow blocking other transaction thread's execution.
The Java thread dump is attached as well.
