Oracle Solution for Error ora-30772

ORA-30772: opaque types do not have default constructors

What triggered the Error:

Constructor invocation did not succeed, since no user-defined constructors were defined for the opaque type, and since opaque types do not have default constructors.

What should we do to fix it:

Add user-defined constructors to opaque type, or specify a member or static method for the opaque type.
