Knut Anders Hatlen commented on DERBY-4188:
-------------------------------------------
Performing clean-up in a finally block may hide the root cause in case of a
test failure. In this particular case, if enableXplainStyle() fails before
xpltest.sysxplain_resultsets has been created, the finally clause will fail
with "table not found" and we won't see the original exception. I think it
would be better to drop the table outside the finally clause, even if it means
that subsequent test cases may fail, since then at least the root cause is
reported. Alternatively, and perhaps better, we could call JDBC.dropSchema(dmd,
"XPLTEST") from tearDown().
> "XplainStatisticsTest" fails w/ 'The exception 'java.sql.SQLException:
> 'RS_ID' is not a column in table or VTI 'XPLTEST.SYSXPLAIN_RESULTSETS'.' was
> thrown while evaluating an expression.'
