    Description

      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:

      public String eval(Object objArg) { /* ...  */ }
      

      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.
