@ManyToMany is allowed on a field of type whose keys and values are not spec-compliant
--------------------------------------------------------------------------------------

                 Key: OPENJPA-418
                 URL: https://issues.apache.org/jira/browse/OPENJPA-418
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 1.0.0, 0.9.7, 0.9.6, 0.9.0
            Reporter: Patrick Linskey


It is possible to write an object with a Map field declared like so:

    @ManyToMany
    private Map<AllFieldTypes,AllFieldTypes> map =
        new HashMap<AllFieldTypes,AllFieldTypes>();


This should not be possible; instead, we should require @PersistentMap usage, since the behavior above is not spec-compliant.

    @PersistentMap
    private Map<AllFieldTypes,AllFieldTypes> map =
        new HashMap<AllFieldTypes,AllFieldTypes>();

Or, if we decide to support @ManyToMany usage, we must review the code in the PersistenceMetaDataParsers to make sure that we're doing the right things, especially with keys. It looks like @ManyToMany and @PersistentMap are handled very differently in that code.
