/**
* Test for https://issues.jboss.org/browse/ISPN-2383.
*
* A single execution of this test (or multiple for that reason)
* might not verify the tested condition( that is a transaction is not lost when the main owner of the single key it
* touched has changed as a result of a node joining). That is because the key is generated before the new node to join
* so we have no guarantees that the key will map to the new joiner (this is what we want to test). Running the test
* several times significantly increases the chances for this happen.
