[jbossts-issues] [JBoss JIRA] (JBTM-3058) Add STM tests that verify nested transactions are closed

[Michael Musgrove (JIRA)]

     [ https://issues.jboss.org/browse/JBTM-3058?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michael Musgrove updated JBTM-3058:
-----------------------------------
    Description: 
STM implements "Closed Nested Transactions" as opposed to Flattened or Open. We need a test which demonstrates that nested transactions follow the closed model.

Furthermore, STM implementations can differ in how transactional code and non-transactional code are isolated from each other (with respect to visibility of updates during a transaction). Add a test that verifies that we use the "Weak Isolation" model.

Details of the expected behaviour is covered in the Sept 2018 jbossts blog entitled "[Tips on how to evaluate STM implementations|http://example.com|https://jbossts.blogspot.com/2018/09/tips-on-how-to-evaluate-stm.html]"
