  14)Make sure the space padding at the end of various character datatypes is implemented
commented correctly in javadocs. This padding is used in collation related methods. For eg
check SQLChar.stringCompare method.
  
  == Implemented items ==
- 1)A shell for subclass of SQLChar has been implemented and it is called CollatorSQLChar.
It resides in derby.iapi.types package. This work was done by revisions 516864, 516869 and
518479.
+ 1)Subclasses with non-default-collation have been implemented for character types SQLChar,
SQLVarchar, SQLLongvarchar and SQLClob. The new subcalsses are called CollatorSQLChar, CollatorSQLVarchar,
CollatorSQLLongvarchar and CollatorSQLClob, respectively. They reside in derby.iapi.types
package. This work was done by revisions 516864, 516869 and 518479, 524545.
  
  2)At the time of database create time, optional JDBC url attribute COLLATION is validated
by the boot code in data dictionary and the validated value of COLLATION(if none specified
by user, then it will default to UCS_BASIC which is also the only collation available on pre-10.3
databases) attribute is saved as derby.database.collation property in the properties conglomerate.
This work was done by revision 511283
