Hi, Erik,
Does this extension work with SchemaTool also? When I try it I get:

Subject: Collections of interfaces
Javadogs,
The JPOX team has pointed out that JDO doesn't require support for Collections of interfaces as persistent field types.
Clearly, this was an oversight, as it was meant to be required and there are actually TCK tests for it.
I'd like to correct the oversight in the JDO 2.0 spec.
So I need to know:
Are there any JDO implementations that do not support this? All implementations that claimed to pass the TCK should have run into this...
Thanks,
Craig
