Commit 15b0f1cfc2d022005c90f4852a2696b19c5ac816 in nifi's branch
refs/heads/master from Gary Teichrow
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=15b0f1c ]
NIFI-6320. This closes #3494. Added a check whereby, if the user is using the
"Use Segment Names" option in the ExtractHL7Attributes processor and the HL7
message being processed contains custom user segments (e.g., Z Segments), the
code will downgrade to returning the Segment Label as it does when this option
is not used. Without this a null pointer is thrown at line 288.

> If a user is processing an HL7 message that contains custom segments (e.g. Z
> segments), an NPE is thrown at line 288 in ExtractHL7Attributes.java upon
> encountering that segment. The call to segment.getNames() will return a list
> of Nulls from HAPI for this custom segment.
