If rollback fails, then the original exception is not being thrown.

It looks like if the rollback fails with "Rollback failed. There is no active transaction.", then we never find out what the original exception was about.

I have this happening, for whatever reason the rollback fails. Could be improved by wrapping the rollback in another try catch and appending the exception to the previous one. What do you think?
