    [ https://issues.apache.org/jira/browse/MINIFI-252?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15991228#comment-15991228 ] 

Kevin Doran commented on MINIFI-252:
------------------------------------

I did a bit of research and found what appears to be a clean and simple way of doing this by using `std::set_terminate` to set a global handler: http://en.cppreference.com/w/cpp/error/set_terminate

Here is a detailed stack overflow answer containing some recommendations on the practice:

> With no claim on a resource, FILE_OPERATION_EXCEPTION is thrown, but not logged or caught. It is silently dropped. Java has a concept of an uncaught exception handler. We need to implement something like this so that we can know what to do in this case. At the very least a log message should be generated and roll back the session if it is not.
