  invoking compareTo(Date) method.  The compare will throw a
  ClassCastException when the parameter is a instance of Date but
  Timestamp.
  .
  Stack Trace: java.lang.ClassCastException: java.util.Date
  incompatible with java.sql.Timestamp
   at java.sql.Timestamp.compareTo(Unknown Source)
  .
  

Local fix

Problem summary

• compareTo(Date) method will cast the parameter of Date to
  Timestamp when comparing these two instances. If the parameter
  is a instance of Date rather than a Timestamp, it will throw the
  ClassCastException.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR3
  .
  When comparing a Timestamp with Date, cast the instance type to
  Timestamp if and only if it is a instance of Timestamp. If it is
  a Date, compare diretly by their time value without casting.
