Description

In JDK7, it will throw out NPE if put a NULL into a TreeSet. And in the unit tests, user can add a NULL as qualifier into the family map for GET or SCAN.
So we shall do the followings:

1) Make sure the semantics of NULL column qualifier is equal to that of the EMPYT_BYTE_ARRAY column qualifier.

2) An easy fix is to use the EMPYT_BYTE_ARRAY qualifier to replace NULL qualifier in the family map for the GET or SCAN objects, and everything else shall be backward compatible.

3) Add a jdk option in the pom.xml (Assuming user installed the fb packaged jdk)
eg: mvn test -Dtest=TestFromClientSide -Pjdk7
