Hibernate - function rand() in MYSQLDialect

I noticed that the MYSQLDialect defines rand() function as:

registerFunction("rand", new NoArgSQLFunction("rand", StandardBasicTypes.DOUBLE));

But, mysql allows use this function with argument (seed). [ approve ]

I have extended MySQLDialect and redefined this function and my code works correctly now. Nonetheless i want to know - this is bug or feature? Should i create an issue in hibernate bug tracker?

hibernate version: 4.3.6.Final

Yes this is bug.. I found the open issue in hibernate bug tracker.
