Michelle Caisse commented on JDO-453:
-------------------------------------

From the spec (assertion numbers need to be added):

Object newInstance(Class persistenceCapable);

A12.6.6-1 [The parameter must be one of the following:
-  an abstract class that is declared in the metadata as persistence-capable
, in which all abstract methods are declared as persistent properties, or
-  an interface that is declared in the metadata as persistence-capable, in 
which all methods are declared as persistent properties, or
-  a concrete class that is declared in the metadata as persistence-capable.
 In this case, the concrete class must declare a public no-args constructor.

If the parameter does not satisfy the above requirements, JDOUserException i
s thrown.]
...
A12.6.6-2 [In order for the newInstance method to be used, the parameter
 interface must be completely mapped. For relational implementations, the in
terface must be mapped to a table and all persistent properties must be mapp
ed to columns. Additionally, in
terfaces that are the targets of all relationships from persistent propertie
s must also be mapped. Otherwise, JDOUserException is thrown by the newInsta
nce method.]

> New test cases are needed for illegal arguments of newInstance.
> One strategy is to define classes in a new package along with metadata, bu
t no mapping (since these are error classes). A new test should try to insta
ntiate the classes using the newInstance method and verify that JDOUserExcep
tion is thrown.
> Classes to test include:
> Abstract class with abstract method not declared as a property (missing me
tadata for the method)
> Interface with method not declared as a property (missing metadata for the
 method)
> Concrete class with missing public no-args constructor
