Kirby Linvill updated NIFI-3142:
--------------------------------
    Status: Open  (was: Patch Available)

Additional logic should be added to catch seen exceptions rather than catching all exceptions in general to prevent the possibility of data loss. As a result, I am cancelling this patch.

> The ExtractHL7Attribute processor will not route a flowfile to REL_FAILURE if processing the flow file throws an exception that is not an HL7Exception. This bug is a result of the try catch block in the onTrigger method. It is easily fixed by changing the catch block to catch a throwable object. Change
> {noformat} 
> try {
>     ...
> } catch (final HL7Exception e) {
>     getLogger().error("Failed to extract attributes from {} due to {}", new Object[]{flowFile, e}, e);
>     session.transfer(flowFile, REL_FAILURE);
>     return;
> }
> {noformat} 
> to 
> {noformat} 
> try {
>     ...
> } catch (final Throwable t) {
>     getLogger().error("Failed to extract attributes from {} due to {}", new Object[]{flowFile, t}, t);
>     session.transfer(flowFile, REL_FAILURE);
>     return;
> }
> {noformat}
