> Many a times we see conflict exception in the logs like below. Looking at the stacktrace its hard to reason out what was the conflict and hence harder to debug such issues. Oak should provide more details as part of exception message itself to simplify debugging such issues.
> Note that such issues are intermittent and might happen in background processing logic. So its required that all details should be made part of exception message itself as it would not be possible to turn on any trace logging to get more details given the intermittent nature of such issues
