--------------------------------------
> 2) If the Derby engine is running on Java 5 or later, then the
> resolution rules are the OldRules with the following change: The SQL
> Standard, part 13, section 8.6, refers to the resolution rules
> described in The Java Language Specification, Second Edition. Replace
> that with a reference to the resolution rules in The Java Language
> Specification, Third Edition.
I think we should allow ourselves to regard the standard's intent
rather than letter here: JAVA PARAMETER STYLE should be allowed to
resolve to varargs when running on Java 5 or later, since this is a
now a part of Java. (As well as for DERBY_JDBC_RESULT_SET).
> 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.
