Error description
DatabaseMetaData class methods for quoted identifers, such as storesLowerCaseQuotedIdentifiers, SupportsMixedCaseQuotedIdentifiers(), StoresMixedCaseQuotedIdentifiers() returns True if called against DB2 database on iseries. But it should return False because, From the JDBC definition of storesMixedCaseQuotedIdentifiers(), the value returned will be true only if the database 1) treats mixed case quoted SQL identifiers as case insensitive. 2) and stores them in mixed case. Therefore, storesMixedCaseQuotedIdentifiers() should return false since DB2 doesn't treat them as case insensitive. The result should be the same for other metadata functions too. The same functions return False against DB2 on Luw and ZOS.
