'Not-Constant' Annotation Parameters using JDO in Scala 2.8

Hi,

I am recently facing the following problem when trying to use the JDO annotations with the new syntax of Scala 2.8 (2.8.0.r20733-b20100130020228)
(various sources indicate it was possible in < 2.8)
#################
import javax.jdo.annotations.{IdGeneratorStrategy, PrimaryKey, Persistent, PersistenceCapable, IdentityType}

@PersistenceCapable(identityType = IdentityType.APPLICATION)
class TestObject(@PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) val key : Long) {

}
#################

This results in the following compile-time error. Eclipse indicates:
#################
"annotation argument needs to be a constant; found: IdGeneratorStrategy{<null>}.IDENTITY{<null>}"
#################

Looking up the class I can see that it actually is a 'constant enum':
http://db.apache.org/jdo/api21/apidocs/javax/jdo/annotations/IdGeneratorStrategy.html
#################
IDENTITY
public static final IdGeneratorStrategy IDENTITY
#################

So I wonder how to fix this or if there is a workaround know for these kind of issues.

Best Regards,
Nicolas
