Sounds good, thanks [~markap14]

> If we write to the Content Repository and get an IOException (for example,
> out of disk space), the ProcessSession catches this and then removes the
> temporary content claim and then throws a FlowFileAccessException. However,
> the entire session really should be rolled back, because the FlowFIle no
> longer has a valid Content Claim. An example of this is in the
> StandardProcessSession.write method:
> {code}
> } catch (final FlowFileAccessException ffae) {
> resetWriteClaims(); // need to reset write claim before we can
> remove the claim
> destroyContent(newClaim);
> throw ffae;
> }
> {code}
> Processors that then catch Throwable or the general Exception and route to
> failure pass along an invalid FlowFile. We end up seeing the following in the
> logs:
> {code}
