Summary: intermittent test failure in LangScripts schemas
Key: DERBY-6772
URL: https://issues.apache.org/jira/browse/DERBY-6772
Project: Derby
Issue Type: Bug
Components: Test
Affects Versions: 10.12.0.0
Environment: windows 2008, ibm 1.7
Reporter: Myrna van Lunteren
I saw a failure in LangScripts schemas.sql on a trunk test run on windows 2008
with ibm 1.7:
{noformat}

schemas(org.apache.derbyTesting.functionTests.tests.lang.LangScripts)junit.framework.ComparisonFailure:
Output at line 477 expected:<... |[BTREE (1)] > but
was:<... |[NULL ] >

See:

Without code changes this same test passed fine with other jvms.
The diff is resulting from this query:
{noformat}
select schemaname, tablename, descriptor as descr
from sys.sysschemas s, sys.sysconglomerates c , sys.systables t
where CAST(t.tablename AS VARCHAR(128)) = 'SAMPLETAB'
and s.schemaid = c.schemaid
and c.tableid = t.tableid
order by schemaname, tablename;
{noformat}
This gives three rows: In the master file (removed some spaces for display):
{noformat}
SCHEMANAME |TABLENAME |DESCR
-------------------------------------------------------------------------
APP |SAMPLETAB |NULL
TEST |SAMPLETAB |BTREE (1)
TEST |SAMPLETAB |NULL
{noformat}
In the failed situation, the 'TEST' rows are ordered differently.
