> This ticket is to enable generic Object type as element type by using SQL ANY
> in parameter / argument type mapping.
> This will enable support for use case such as:
> {code:java}
> public String eval(Object objArg) { /* ... */ }
> {code}
> The changes require here:
> 1. Introduce wildcard search and search rules for SQL ANY type usage.
> 2. Enabling wildcard search when concrete type search returns no match.
