[HAPI-devel] bug: Varies class called to fix varies OBX segment in v2.1, but field 5 isn't "Varies" in v2.1

Hi.

If I send a v2.1 message with an OBX segment to hapi, it crashes thusly:

The offending line (107) in Varies tries to cast field 5 to a Varies  
type, which it is in later versions of hl7. But in v2.1, it's not a  
Varies.  Hence, class cast exception.

I fixed my local copy by tossing in a catch ClassCastException  
statement at the bottom of fixOBX5, which just returns silently.  Not  
sure what else it should do for v2.1....
