             Summary: Init store failure could provide more information in the exception than just NullPointer
                 Key: JBTM-3134
                 URL: https://issues.jboss.org/browse/JBTM-3134
             Project: JBoss Transaction Manager
          Issue Type: Enhancement
    Affects Versions: 5.9.5.Final
            Reporter: Ondrej Chaloupka
            Assignee: Ondrej Chaloupka


When `StorageManager` fails with to initialize store instance the error comes as `NullPointerException`. That's not much informative. The exception should says what happens. The example of the exception thrown now is[1]. The more information then is available in the log but still exception should give some basic idea what happens not just `NullPointerException`.
