This page list the work planned for the JDO 2.1 Maintenance Release. The work may involve updating the specification, changing the api, and/or adding tests or modifying tests in the TCK.
The task to adapt the JDO sources to the new apache license policy is completed, see FixingLicenseHeader for details.

In 5.4.1, Compound Identity should be updated to reflect that for key fields of reference types, the type of the key field is the reference type in the class but the oid of the reference type in the oid class. |

In 6.4.3, change "Portable JDO applications must not depend on whether instances of these classes are treated as SCOs or FCOs. " to "Portable JDO applications must not depend on SCO or FCO uniquing behavior, nor 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." JDO-397 |

In 12.6.6, clarify that a JDOUserException will be thrown when invoking newInstance: if a class is not persistence-capable, or does not declare a public no-args constructor; if an interface is not persistence-capable or declares methods that are not defined as persistent properties; if an abstract class is not persistence-capable or declares abstract methods that are not defined as persistent properties.

done |
|

Add to 14.6.9: Projected SCOs are never owned, projected FCOs are always managed. Modifying unowned SCOs never has an effect on the database. Modifying FCOs no matter how you get them always has an effect if the tx commits. |

Add to 15.1 a paragraph describing that mapping an enum to a fixed-precision numeric type uses the ordinal() value for storage; mapping to a character column type (CHAR, VARCHAR, etc.) uses the name() value for storage; mapping to any other column type is an error. JDO-546 |

Provide in a new chapter a set of annotations that map directly to xml elements as an alternative to using xml metadata. Describe how jdo implementations can use either JDO annotations or JPA annotations to provide metadata. JDO-451 details JDO-503 |
