Craig Russell resolved JDO-397.
-------------------------------

Resolution: Fixed

The 2.1 specification now states:

Portable JDO applications must not depend on SCO or FCO uniquing behavior, n
or on the storage
mechanism in the datastore. Portable applications may use the same instance 
of these classes as field
values in any persistence-capable class instance.

This should resolve this issue.

> Locale instances are shared by different PMs (when in use as FCO)

> Tests in org.apache.jdo.tck.models.fieldtypes are using fields of Locale that are 
defined as FCO. The definition is only a hint to the implementation but when a FCO i
s actually used, the same JVM static Locale instances are persisted using different 
Per
sistenceManagers and tests fail.
