• Closed as suggestion for future release.

Error description

• EclipseLink generates preallocated sequence values at NEXTVAL
  - allocationSize. This strategy causes an incompatibility with
  other jpa providers, namely OpenJPA, that expects ID values to
  be beyond NEXTVAL. This PMR provides an enhancement to
  EclipseLink in for form of a new persistence property that
  allows the behavior to change and add compatibility to
  existing tables IDs from other jpa providers.
  
  The new persistence property is this:
  <property
  name="eclipselink.sequencing.start-sequence-at-nextval"
  value="true"/>
  
  With this property set, EclipseLink will start generating
  sequence ID values from NEXTVAL forward, instead of the default
  behavior of starting at (NEXTVAL - size).
  
  Note that the default behaviour remains "as-is".
  This APAR was taken to ship this new support.
  Please read the responder page in case of changes to the final
  code behaviour.
