Ondrej Chaloupka created JBTM-3153: -------------------------------------- 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.)
