    Make sure you're using the correct and most up-to-date oracle driver.
    The crash is happening in your oracle driver, so it's unlikely to be a
    cayenne problem.
    Since the only thing that changed was your development environment, again,
    it's probably the driver that changed rather than cayenne.
