Knut Anders Hatlen commented on DERBY-4753:
-------------------------------------------
This is most likely going to work with the latest 10.7 development sources
because FALSE is now accepted also in non-internal SQL, and the failing call to
checkInternalFeature() from SQLParser.literal() has been removed. But,
regardless of that, it looks like we have a bug that makes the compiler context
lose the knowledge about it being an internal statement. Too bad we don't have
a reliable repro for it.

> Key: DERBY-4753
> URL: https://issues.apache.org/jira/browse/DERBY-4753
> Project: Derby
> Issue Type: Bug
> Components: JDBC
> Affects Versions: 10.5.3.0
> Environment: Linux
> Reporter: Craig Chaney
>
> We are seeing the failure below occasionally. It does not happen every time
> ... with the exact same database and call sequence it will happen about 1 out
> of 3 times.
> The parameters on the getIndexInfo call are
> connection.getMetaData().getIndexInfo(null, schemaName, tableName, false,
> false);
> schemaName and tableName are valid and definitely not null.
> Caused by:
> java.sql.SQLException: Syntax error: FALSE.
