--------------------------------------
Summary: Possible race condition at jts integration test
com.arjuna.ats.jta.distributed.SimpleIsolatedServers
Key: JBTM-3153
URL: https://issues.jboss.org/browse/JBTM-3153
Project: JBoss Transaction Manager
Issue Type: Bug
Components: Testing
Affects Versions: 5.9.5.Final
Reporter: Ondrej Chaloupka
Assignee: Ondrej Chaloupka
There is a possible race condition at the test `SipleIsolatedServers`
(https://github.com/jbosstm/narayana/blob/5.9.5.Final/ArjunaJTS/integratio...)
where `while loop` can be infinite as the counter never gets expected number of `2`.
This can happen in case of the recovery fails with some unexpected exception/error. For
example the CI experienced `java.lang.LinkageError` on JDK11.
(The exact reason for the linkage error is for further investigation. But the test should
be fixed.)
