Daniel John Debrunner commented on DERBY-3069:
----------------------------------------------
Section 8.6 of part 13 is very precise on the method resolution. It even
mentions "The Java Language Specification, Second Edition" in one section.
Can you be more explicit on what you see in the "last paragraph of section
4.2.2" that leads you to believe that Java method resolution is followed?
Note that Java method resolution is not followed by the SQL Standard, e.g. a
VARCHAR() column will not map to a java parameter of type Object
and a DECIMAL parameter will not map to an Object or Number.
> Derby does not resolve functions bound to methods with varargs.

> Varargs were added in Java 5. It would be nice if Derby let you invoke a
> function bound to a method with a variable length argument list. The
> Reference Guide states a small number of restrictions for methods which can
> be invoked as Derby functions: They must be public, static, and not have
> arguments which are long datatypes. I see no reason that Derby shouldn't be
> able to resolve and invoke functions which are bound to methods which don't
> suffer these limitations but which have variable argument lists.
