----------------------------------------
Hi, Liyin.
About this issue, Jimmy Xiang fixed null qualifier
[HBASE-7130|https://issues.apache.org/jira/browse/HBASE-7130], and the jdk7
profile on maven is opened yet to be implemented?
> [89-fb] Fix the NPE in unit tests for JDK7
> ------------------------------------------
>
> Key: HBASE-7106
> URL: https://issues.apache.org/jira/browse/HBASE-7106
> Project: HBase
> Issue Type: Improvement
> Reporter: Liyin Tang
> Priority: Trivial
>
> 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
