[ https://issues.jboss.org/browse/JBTM-3153?page=com.atlassian.jira.plugin.... ] Ondrej Chaloupka updated JBTM-3153: ----------------------------------- Description: 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.)
