> I saw a failure in LangScripts schemas.sql on a trunk test run on windows
> 2008 with ibm 1.7:
> {noformat}
> 1)
> schemas(org.apache.derbyTesting.functionTests.tests.lang.LangScripts)junit.framework.ComparisonFailure:
> Output at line 477 expected:<... |[BTREE (1)] > but

> See:
> http://people.apache.org/~myrnavl/derby_test_results/main/windows/testSummary-1639825.html
> 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.
