Marcel Baumann commented on ISIS-789:
-------------------------------------
It would be great to support DN 4.0. From the tests I did it is currently not
possible to Java-8 due to ASM library version which does not support Java 8
class file format. Therefore we cannot use the current version of Java in
academic projects or proof of concepts with ISIS. We are somewhat nervous to
see that DN 4.0 support moved form 1.7 to 2.0 release. We would truly
appreciate if support for DN 4.0 and Java 8 is scheduled for 2014.
> Upgrade to DN 4.0

> Key: ISIS-789
> URL: https://issues.apache.org/jira/browse/ISIS-789
> Project: Isis
> Issue Type: Improvement
> Components: Core: Objectstore: JDO
> Affects Versions: objectstore-jdo-1.4.1
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Priority: Minor
> Fix For: core-2.0.0
>
>
> NB: DN 4.0 only supports Java 7, so this is also dependent on our moving to
> Java 7 across board (see ISIS-568).
> NB: should also check ISIS-647 (fix for
> http://www.datanucleus.org/servlet/jira/browse/NUCCORE-1103).
> - will possibly want to enable to get better perf?
> NB: also know that there's a change to the way that polymorphism works, is
> mapped differently (in Estatio).
