manuall upgrade bundled eclipselink in 5.2.0 ?

hi all,

as far as I know, the bundled EclipseLink2 package with JOnAS 5.2.0 is
2.1.2 (from dec. 2010)

Recently I found out that a bugfix release of the 2.1 series was
released on April 15th, EclipseLink 2.1.3

in this release, a deadlock-error in relation with batch-writing was
fixed -- I would treat this as an important bug fix !


is there a way we can upgrade/replace the bundled eclipselink 2.1.2 with
the new 2.1.3 release on our existing JOnAS 5.2.0 instances ?

regards,
hans
