Subject [jira] Commented: (DERBY-2553) values SYSCS_UTIL.SYSCS_GET_RUNTIMESTATISTICS() returns null in test ScrollCursors1Test when run against network server

    [ https://issues.apache.org/jira/browse/DERBY-2553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12994738#comment-12994738
] 

Myrna van Lunteren commented on DERBY-2553:
-------------------------------------------

Interesting. I have been poking at DERBY-1342 for a couple of days now, and so I noticed a
couple of different tests getting runtimestatistics fine with client. So I thought I'd double
check this, and with the if (embedded) condition commented out, the test ran fine (built classes,
insane). I also checked InbetweenTest, which has the same check for if (embedded) (as do a
number of other tests).

Did you actually try it out also?

> Call to runtimestatistics in the new test ScrollCursors1Test returns null value when
run against network server.
> Look for the reference to this bug near the following code.   I was not able to reproduce
this outside of the test.
