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

Add STM tests that verify nested transactions are closed -------------------------------------------------------- Key: JBTM-3058 URL: https://issues.jboss.org/browse/JBTM-3058 Project: JBoss Transaction Manager Issue Type: Bug Components: STM, Testing Affects Versions: 5.9.0.Final Reporter: Michael Musgrove Assignee: Michael Musgrove Priority: Optional Fix For: 5.next 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/t...
