----------------------------------

             Summary: NPE in IndexRowGenerator.getExecutionFactory()

             Project: Derby
          Issue Type: Bug
          Components: Miscellaneous
    Affects Versions: 10.11.1.1
         Environment: Tue Sep 08 19:39:37 EDT 2015:
Booting Derby version The Apache Software Foundation - Apache Derby - 10.11.1.1 - (1616546):

            Reporter: Edward Howe
            Priority: Critical


Derby crashed with the following stack trace while running our application's integration tests.
 This is the first time I've seen this, and cannot reproduce it.  It happened during our application's
startup.  The embedded database had been opened by this point, and some initial queries had
been executed.
