values SYSCS_UTIL.SYSCS_GET_RUNTIMESTATISTICS() returns null

Hi Kathey,
I saw your test conversion of  scrollCursors1.sql and the related issue
values SYSCS_UTIL.SYSCS_GET_RUNTIMESTATISTICS() returns null in test
ScrollCursors1Test when run against network (
http://issues.apache.org/jira/browse/DERBY-2553). When I was converting
outerjoin.sql to JUnit (https://issues.apache.org/jira/browse/DERBY-4424) I
face the same problem and not solved yet.
Can you help me for reasoning for it being null.
Thanks
Eranda
