Description
There is a possible race condition at the test SipleIsolatedServers#testSimultaneousRecover (https://github.com/jbosstm/narayana/blob/5.9.5.Final/ArjunaJTS/integration/src/test/java/com/arjuna/ats/jta/distributed/SimpleIsolatedServers.java#L306) 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.)
